- the side airbag 4, the curtain airbag 2, and the pretensioner 19 are also provided on the passenger seat side. However, in the present embodiment, only the driver seat side is provided for the sake of simplicity. Is described.
- the control unit 11 performs a process of determining whether a driver or a passenger is on the passenger seat in the vehicle based on the detection signal of the load sensor 13. In addition, the control unit 11 calculates an angle in the roll direction of the vehicle by integrating the angular velocity signal output from the roll angular velocity sensor 12, and determines whether the vehicle rolls over based on the angle and the angular velocity. Processing to determine is performed. That is, the control unit 11 also has a function as a rollover detection device. And when it is judged by the control part 11 that a vehicle rolls over, the process which outputs the operation signal for operating the side airbag 4, the pretensioner 19, and the curtain airbag 2 by the procedure mentioned later is performed.
- step S11 of FIG. 6 the control unit 11 determines whether or not a vehicle rollover is detected. As described above, this process is performed based on the angular velocity output from the roll angular velocity sensor 12 and the angle obtained by integrating the angular velocity. Then, when the vehicle rotates in the roll direction (the direction of the arrow Y1 in FIG. 2) from the angular velocity and angle, and the vehicle cannot be overturned (when it is certain that the vehicle rolls over), the control unit 11 detects rollover. Note that the control unit 11 may estimate the rollover of the vehicle.
- the occupant 5 of the vehicle 1 moves to the outside of the vehicle by the inertial force caused by the lateral deceleration generated by the skidding before the roll. Therefore, the space between the head of the occupant 5 and the vehicle side wall 3 (door, glass, pillar, etc.) is reduced.
- the occupant 5 rotates together with the vehicle 1 when the angle of the roll direction of the vehicle 1 is small. Therefore, the curtain airbag is deployed in a situation where there is little space between the head of the occupant 5 and the vehicle side wall.
- the curtain airbag may be caught on the head of the occupant 5 or the curtain airbag may be deployed inside the vehicle with respect to the occupant's head, and the curtain airbag cannot be smoothly deployed. Become. In the present embodiment, this situation is avoided by the following operation.
- step S11 If rollover of the vehicle is detected (YES in step S11), the process proceeds to step S12.
- step S12 the control unit 11 outputs a driving signal to the airbag driving unit 15 to deploy the side airbag 4.
- the control unit 11 outputs a driving signal to the airbag driving unit 15 to deploy the side airbag 4.
- step S13 the control unit 11 operates the timer 14 to measure a first predetermined time (for example, 30 msec).
- step S14 it is determined whether or not 30 msec has been timed. If 30 msec has been timed, the process proceeds to step S15.
- step S15 the control unit 11 outputs an operation signal to the pretensioner driving unit 16 to operate the pretensioner 19.
- the pretensioner 19 pulls the seat belt 6 upward, the seat belt 6 presses the occupant 5 toward the seat back side and maintains the posture of the occupant 5 that has moved to the inside of the vehicle. .
- a space for deploying the curtain airbag 2 that is, a space between the occupant's head and the vehicle side wall 3 can be maintained.
- step S16 the control unit 11 operates the timer 14 to measure a second predetermined time (for example, 30 msec).
- step S17 it is determined whether or not 30 msec has been timed. If 30 msec has been timed, the process proceeds to step S18.
- step S18 the control unit 11 outputs a driving signal to the airbag driving unit 15 to deploy the curtain airbag 2.
- the curtain airbag 2 is deployed in a state in which a space between the head of the occupant and the vehicle side wall 3 is secured, and the curtain airbag 2 is reliably deployed. Can do. That is, even when the vehicle starts rotating in the roll direction and the vehicle rollover starts from a state where the occupant 5 approaches the vehicle side wall 3, the curtain airbag 2 can be smoothly deployed.
- the side airbag is used. 4 is deployed to move the occupant 5 to the inside of the vehicle. Thereafter, after a first predetermined time (for example, 30 msec) has elapsed, the pretensioner 19 is activated to fix the occupant 5 to the seat back. Therefore, the occupant's head can be easily separated from the vehicle side wall 3, and a space for deploying the curtain airbag 2 can be reliably ensured between the occupant's head and the vehicle side wall 3.
- a first predetermined time for example, 30 msec
- FIG. 7 is a block diagram illustrating a configuration of an occupant restraint device 200 according to the second embodiment.
- the occupant restraint device 200 according to the present embodiment has two pretensioners 19, a shoulder belt pretensioner 21 and a lap belt pretensioner 22, as compared with the occupant restraint device 100 shown in FIG. 1. It differs in that it is composed of tensioners. That is, as shown in FIG. 8, the seat belt for restraining the occupant includes two lap belts 7 for fixing the occupant's waist to the seat cushion and two shoulder belts 8 for fixing the upper body of the occupant to the seat back.
- the pretensioner includes a lap belt pretensioner 22 that pulls the lap belt 7 toward the vehicle side wall 3 and a shoulder belt pretensioner 21 that pulls the shoulder belt 8 upward.
- a lap belt pretensioner 22 that pulls the lap belt 7 toward the vehicle side wall 3
- a shoulder belt pretensioner 21 that pulls the shoulder belt 8 upward.
- step S31 in FIG. 12 the control unit 11 determines whether or not a vehicle rollover is detected. Similar to the first embodiment described above, this process detects rollover when the vehicle rotates in the roll direction and rollover of the vehicle cannot be avoided. At this time, since the vehicle rolls from side slip to roll over, as shown in FIG. 8, the occupant 5 of the vehicle 1 moves to the outside of the vehicle by the inertial force caused by the lateral deceleration generated by the side slip before rollover. Therefore, the space between the passenger's head and the vehicle side wall 3 (door, glass, pillar, etc.) is reduced. If rollover of the vehicle is detected (YES in step S31), the process proceeds to step S32.
- step S32 the control unit 11 outputs a drive signal to the airbag driving unit 15 to deploy the side airbag 4. Further, in step S33, the control unit 11 outputs an operation signal to the pretensioner driving unit 16 to operate the lap belt pretensioner 22.
- the lap belt pretensioner 22 pulls the lap belt 7 in a short time, as shown in FIG. 9, the lap belt 7 pushes the occupant's waist into the seat cushion and fixes the waist. For this reason, the side airbag 4 that inflates between the occupant 5 and the vehicle side wall 3 moves only the upper body of the occupant 5 toward the inside of the vehicle, and the deployment force generated by the expansion of the side airbag 4 is used as the upper body of the occupant 5. Can focus on. Therefore, the upper body of the occupant 5 can be easily moved to the inside of the vehicle.
- step S34 the control unit 11 operates the timer 14 to measure the first predetermined time (for example, 30 msec).
- step S35 it is determined whether or not 30 msec has been timed. If 30 msec has been timed, the process proceeds to step S36.
- step S36 the control unit 11 outputs an operation signal to the pretensioner driving unit 16 to operate the shoulder belt pretensioner 21.
- the shoulder belt pretensioner 21 pulls the shoulder belt 8 upward as shown in FIG. Therefore, the shoulder belt 8 presses the occupant 5 toward the seat back side and maintains the posture of the occupant 5 that has moved to the inside of the vehicle. As a result, a space for deploying the curtain airbag 2, that is, a space between the occupant's head and the vehicle side wall 3 can be maintained.
- step S37 the control unit 11 operates the timer 14 to measure a second predetermined time (for example, 30 msec).
- step S38 it is determined whether or not 30 msec has been timed. If 30 msec has been timed, the process proceeds to step S39.
- step S39 the control unit 11 outputs a drive signal to the airbag driving unit 15 to deploy the curtain airbag 2.
- the curtain airbag 2 is deployed in a state where a space between the head of the occupant and the vehicle side wall 3 is secured, and the curtain airbag 2 can be deployed reliably. it can. That is, even when the vehicle starts rotating in the roll direction and the vehicle rollover starts from a state where the occupant 5 approaches the vehicle side wall 3, the curtain airbag 2 can be smoothly deployed.
- the lap belt is used.
- the pretensioner 22 is actuated to fix the occupant's waist to the seat cushion.
- the side airbag 4 is deployed to move the occupant 5 to the inside of the vehicle.
- a first predetermined time for example, 30 msec
- the shoulder belt pretensioner 21 is activated to fix the occupant 5 to the seat back. Therefore, a space for deploying the curtain airbag 2 between the occupant's head and the vehicle side wall 3 can be reliably ensured.
- the lap belt pretensioner 22 is operated simultaneously with the deployment of the side airbag 4. However, the lap belt pretensioner 22 is activated before the side airbag 4 is deployed. Therefore.
- FIG. 13 is a block diagram illustrating a configuration of an occupant restraint device 300 according to the third embodiment.
- the occupant restraint device 300 according to the third embodiment is different from the occupant restraint device 100 shown in FIG. 1 in that the seat belt is an electric seat belt 32 and the control unit 11. The difference is that a seat belt control unit 31 that operates under control is provided.
- the electric seat belt 32 is connected to the electric motor 33 at the leading end of the electric seat belt 32 as shown in FIG. Then, by driving the electric motor 33 under the control of the seat belt control unit 31, tension is generated in the electric seat belt 32 to restrain the occupant. Further, the electric seat belt 32 has a function of protecting the occupant by operating when it is necessary to restrain the occupant, such as when the vehicle 1 is suddenly braked.
- the components other than the electric seat belt 32 are the same as those in FIG. 1, and thus the same reference numerals as those in FIG.
- step S51 of FIG. 15 the control unit 11 determines whether or not a vehicle rollover is detected. As described above, this process detects rollover when the vehicle rotates in the roll direction and rollover of the vehicle cannot be avoided. If a vehicle rollover is detected (YES in step S51), the process proceeds to step S52.
- step S52 the control unit 11 determines whether or not a tension is applied to the electric seat belt 32. If the tension is applied, the controller 11 loosens the tension. That is, the passenger's restraint by the electric seat belt 32 is released.
- step S53 the control unit 11 outputs a driving signal to the airbag driving unit 15 to deploy the side airbag 4.
- a space can be provided between the head of the occupant and the vehicle side wall 3.
- the pretensioner 19 is not activated, and no tension is applied to the electric seat belt 32. Therefore, the frictional force between the occupant 5 and the seat back surface is not increased, and a space can be easily formed.
- step S54 the control unit 11 operates the timer 14 to measure the first predetermined time (for example, 30 msec).
- step S55 the control unit 11 determines whether or not 30 msec has been timed. If 30 msec has been timed, the process proceeds to step S56.
- step S56 the control unit 11 outputs an operation signal to the pretensioner driving unit 16 to operate the pretensioner 19.
- the posture of the occupant 5 moved to the inside of the vehicle can be maintained, and the space between the occupant's head and the vehicle side wall 3 can be maintained.
- step S57 the control unit 11 operates the timer 14 to measure a second predetermined time (for example, 30 msec).
- step S58 the control unit 11 determines whether or not 30 msec has elapsed. If 30 msec has been counted, the process proceeds to step S59.
- step S59 the control unit 11 outputs a driving signal to the airbag driving unit 15 to deploy the curtain airbag 2.
- the curtain airbag 2 can be reliably deployed. That is, even when the vehicle starts rotating in the roll direction and the vehicle rollover starts from a state where the occupant 5 approaches the vehicle side wall 3, the curtain airbag 2 can be smoothly deployed.
- the occupant restraint device 300 can achieve the same effects as those of the first embodiment described above. Even when the occupant is restrained by the electric seat belt 32, the side airbag 4 is deployed after the passenger is loosened, so that the electric seat belt 32 is not affected by the restraint.
- occupant restraint device and occupant restraint method of the present invention have been described above based on the illustrated embodiments.
- the present invention is not limited to this, and the configuration of each unit can be replaced with any configuration having the same function.
- both the first predetermined time and the second predetermined time are set to 30 msec.
- the present invention is not limited to this time, and can be set to another time. It is also possible to set the first predetermined time and the second predetermined time to different times.
- the curtain airbag 2 may be deployed without waiting for the second predetermined time (that is, simultaneously).
- the pretensioner when the vehicle starts to roll over, the pretensioner is operated with a delay with respect to the timing at which the side airbag is deployed. Therefore, resistance generated between the occupant and the seat can be reduced, and the occupant can be smoothly returned to the inside of the vehicle. As a result, a space for deploying the curtain airbag can be ensured between the passenger's head and the vehicle sidewall, and the curtain airbag can be smoothly deployed.
