Description

[Detailed Description of the Invention] "Industrial field of application" The present invention has a seat mounted on a vehicle body floor via a seat slide device. The present invention relates to a seat belt device that is fixed to a side portion opposite to a side wall of a vehicle body via a bracket.

"Prior Art" As a conventional seat belt device, for example, there is one as shown in FIG.

That is, the seat frame 3 is mounted on the vehicle body floor 1 side through the seat slide device 2, and the retractor 5 that can extend and retract the webbing 4 to the vehicle body side wall side is a side portion of the seat frame 3 opposite to the vehicle body side wall side. The bracket 6 is fixedly attached to the bracket 6 with its upper half protruding.

The lower end portion of the bracket 6 is a claw portion 7, and the claw portion 7
Is normally fitted to the groove member 8 fixed to the vehicle body floor 1 side so as to be movable back and forth in accordance with the front and rear movement of the seat frame 3,
When the retractor 5 receives a peeling load via the webbing 4, the retractor 5 is locked to the groove member 8 to prevent the retractor 5 from moving upward.

[Problems to be solved by the invention] However, in such a conventional seat belt device, when the retractor 5 receives a peeling load, the bracket 6
By engaging the claw portion 7 with the groove member 8, it is possible to prevent the retractor 5 from moving in the upward direction, but when the webbing 4 is pulled toward the vehicle body side wall, the retractor 5 is centered near the lower portion. Then, the retractor 5 falls down toward the side wall of the vehicle body, and the retractor 5 does not properly wind around the seated person, resulting in poor restraint.

The present invention has been made in view of such a conventional problem, and prevents the retractor from falling toward the side wall of the vehicle body under a peeling load with a bracket or the like to improve the restraint property by webbing. An object of the present invention is to provide a seat belt device that can be used.

[Means for Solving the Problem] The gist of the present invention for achieving such an object is that a seat is mounted on a vehicle body floor via a seat slide device, and a webbing is extended to the side wall of the vehicle body A seat belt device in which a possible retractor is fixed to a side portion of a seat opposite to a side wall of a vehicle body via a bracket, and the retractor is fitted to a groove member fixed to a vehicle body so as to be movable back and forth. At the same time, a claw part that engages with the groove member is formed on the bracket to prevent the retractor from moving upward when the retractor receives a peeling load via the webbing, and the retractor is fitted so that it can move back and forth. In addition, when the retractor receives the peeling load and tries to fall toward the side wall of the vehicle body, the retractor is locked to the retractor from a position opposite to the side wall of the vehicle body with respect to the retractor. The seat belt device is characterized in that an engaging member for preventing the vehicle from falling is fixedly provided on the vehicle body floor side.

"Operation" In the case where the bracket is formed with the claw portion for preventing the retractor from moving upward and the engaging member for preventing the retractor tilting is fixedly provided on the vehicle body floor side, when a peeling load is applied to the retractor through the webbing, When the is pulled upward, the claw portion of the bracket is locked in the groove member on the vehicle body side, and prevents the upward movement.

When the retractor tries to fall to the side wall of the vehicle body, the engaging member on the vehicle body floor side engages with the retractor side, whereby
It is possible to prevent the retractor from falling toward the side wall of the vehicle body.

That is, even when the retractor receives a peeling load, the normal state is maintained, the webbing is appropriately wound around the seated person, and the restraint property can be improved.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

1 and 2 show an embodiment of the present invention.

As shown in FIGS. 1 and 2, the vehicle body floor 10 includes
A seat 30a is mounted via a seat slide device 20a including a pair of rail units 20,20.

That is, the mounting bracket 12 is fixedly mounted on the floor tunnel wall portion 11, and the mounting bracket 12 is provided with a groove member 15 in which a portion having an inverted U-shaped cross section is extended in the front-rear direction. A rail unit 20 on the side wall of the vehicle body is mounted.

The rail unit 20 includes a seat-side rail 21 and a vehicle-body-side rail 22 that are movable in the front-rear direction.
A frame 35 of the seat cushion 30 is fixed to the seat 21. The frame 35 is located below the seat cushion 30, and the upper end of the side wall portion 36 of the frame 35 opposite to the side wall of the vehicle body is located at an intermediate portion in the vertical direction of the side portion 31 of the seat cushion 30.

The upper end of the side wall 36 of the frame 35 is almost
The bracket 40a adapted to be fitted to the upper end portion of the retractor 35 and the retractor 50 in which the vehicle body side wall side surface 57 is closely attached to the bracket 40a are attached to the bolt 38 at the lower end portion 53 of the retractor 50.
It is fastened together by.

The retractor 50 is a shoulder retractor configured so as to be able to be extended and extended to the side wall of the vehicle body of the webbing 60.

The lower end of the bracket 40 is fitted in the groove member 15 so as to be movable in the front-rear direction, and a U-shape is provided so as to prevent the retractor 50 from moving upward when the retractor 50 receives a peeling load via the webbing 60. The claw portion 45 is bent into a shape and is locked to the groove member 15.

A base member 55 of the retractor 50 extends through the bottom surface side of the retractor 50 at a position opposite to the side wall of the vehicle body, and the extended end portion is bent upward to form a flange portion 56.
When the retractor 50 tries to fall toward the side wall of the vehicle body due to the peeling load, the retractor 50 falls from the position opposite to the side wall of the retractor 50 to the flange portion 56 of the base member 55 of the retractor 50. An engagement member 16 that blocks the above is fixed to the floor tunnel top surface portion 11a.

An inner buckle 70 capable of locking the end portion of the webbing wound around the body is attached to the bracket 40 at the front position of the retractor 50.

Next, the operation will be described.

When the rail 21 on the vehicle body side is moved back and forth to adjust the seat 30a forward and backward, the frame 35 moves back and forth, and the bracket 40
Also moves back and forth integrally, and the claw portion 45 of the bracket 40 also has a groove member.
It moves back and forth while it is fitted to 14.

When the peeling load is applied to the retractor 50 via the webbing 60, the retractor 50 is pulled upward and tends to fall toward the side wall of the vehicle body around the lower end portion 53 as a center.

When the retractor 50 is pulled upward, the claw portion 45 of the bracket 40 engages with the groove member 15 on the vehicle body floor 10 side, thereby preventing the retractor 50 from moving upward.

When the retractor 50 tries to fall toward the vehicle body side wall around the vicinity of the lower end portion 53, the engagement member 16 is locked to the flange 56 of the base member 55 from a position opposite to the vehicle body side wall with respect to the retractor 50. And prevents the retractor 50 from falling.

That is, even if a peeling load is applied to the retractor 50, the retractor 50 is not pulled up, does not fall to the side wall of the vehicle body, maintains a substantially normal posture, and the webbing 60 remains wrapped around the seated person in an appropriate state. .

[Advantage of Invention] According to the seatbelt device of the present invention, the bracket supporting the retractor is provided with the claw portion, and the vehicle body floor side is provided with the engaging member engageable with the retractor.
When the retractor receives a peeling load, the claws can prevent the retractor from moving upward and the engaging member can prevent the retractor from falling to the side wall of the vehicle body. Remains properly wound around the seated person, and the restraint can be further improved.
