Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a movable seat for a vehicle that can be made into a seat with a wide seat by combining two infant seats.

[Prior Art] Conventionally, among the front and rear seats arranged on the floor at a predetermined distance, the rear seats are fixed seats, and the front seats can be reconfigured into a seat with a wide seat area that is continuous with the fixed seat. is proposed in Utility Model Application No. 119981/1983. That is, as shown in FIG. 1, links 10 and 16 are connected by pins 12 and 15 to a frame 14 that supports the seat part 2 of the front seat A, and the lower ends of these links are connected to a bracket 8 fixed to a floor 35 by a pin. 9 and 7, and the pillar 4 of the backrest 3 is removably supported in a hole 5 formed integrally in the link 16, and the seat 2 of the front seat A is connected to the seat 22 of the rear seat B. If you want to approach the seat 2, pull out the backrest 3 and
move backwards.

However, in the above-mentioned seat, the bracket 8 that supports the quadrilateral link on the floor protrudes to the rear of the front seat A, which obstructs access to and from the rear seat B, posing a risk of the occupant falling over.

[Problems to be Solved by the Invention] In view of the above-mentioned problems, an object of the present invention is to provide a movable seat for a vehicle that can be combined with a rear seat without obstructing access to the rear seat.

[Means for Solving the Problems] In order to achieve the above object, the configuration of the present invention is such that the front legs are fixed to the seat of a movable seat arranged in front of a fixed seat, and the front legs can be tilted back and forth between them and the floor. The bent part of the inverted L-shaped rear leg is connected to the lower end of the short rear link that is connected parallel to the front link to the seat, and the arm of the rear leg is connected to the middle part of the front link. These are connected to prevent the rear legs from protruding to the rear of the movable seat.

[Function] When used as a seat for infants, the seat portion 2 is supported on the floor 35 by the front legs 13 and the rear legs 33. At this time, since the rear legs 33 are in an upright state, there are no obstacles in the path in front of the rear seat B, and the occupant will not trip. On the other hand, the seat part 2 of the front seat A is replaced with the seat part 2 of the rear seat B.
2, remove the backrest 3 and tilt the front link 10 backwards using the pin 9 as a fulcrum, the rear legs 33 will move in parallel, the seat 2 will touch the seat 22, and the front It is supported on the floor 35 by the lower link 10 and the rear legs 33.

[Embodiment of the invention] As shown in Fig. 2, the front seat A consists of a seat part 2 and a back rest 3, and front legs 13 are fixed to the front end of a frame 14 that supports the seat part 2. pins 12, 15
The front link 10 and the rear link 36, which are parallel to each other, are connected. The lower end of the front link 10 is connected by a pin 9 to a bracket 18 fixed to the floor 35. The lower half of the rear link 36 is cut out, and the rear link 36 is integrally formed with a backrest support part that abuts the rear end of the frame 14 and has a hole 5. The backrest 3 is supported by inserting the support 4 into the hole 5.

According to the present invention, the arm 33a of the inverted L-shaped rear leg 33 is connected to the intermediate portion of the front link 10 by the pin 31, and the bent part of the rear leg 33 is connected to the lower end of the rear link 36 by the pin 32. Ru.

A substantially triangular locking plate 42 having two notches is supported by a pin 41 in the middle portion of the frame 14;
It is engaged with one of the pin 43 of the front link 10 and the pin 44 of the rear link 36. Rear seat B is seat part 2
2 and a backrest 23, these are connected to a J-shaped frame 24, and are attached to the floor 3 by front legs 25 and rear legs 26.
It is fixed at 5. This is common.

Next, the operation of the seat according to the present invention will be explained. When used as a general seat, the front seat A is supported on a floor 35 by front legs 13 and rear legs 33, as shown in FIG. In order to prevent the seat from moving back and forth due to vehicle acceleration, braking, etc., the front link 1
The notch of the lock plate 42 is locked to the pin 43 of 0.

When the front seat A and the rear seat B are combined to form a seat with a wide seat area, the support column 4 is pulled out from the hole 5 and the backrest 3 is removed, as shown in FIG. Lock plate 4
2 and the pin 43, and move the seat part 2 rearward while lifting it, the front link 10 is moved to the pin 9.
The rear leg 33 tilts rearward around the center, and the rear legs 33 move backward in parallel.

horizontal arm 33a of the rear leg 33, front link 10,
The rear link 36 and the frame 14 constitute a quadrilateral link, and the seat 2 is pressed against the front end of the seat 22. When the notch of the lock plate 42 is engaged with the pin 44 of the rear link 36, a wider seat is formed by the seats 2, 22, and the rear link 36 is fixed by the lock plate 42 even when the vehicle accelerates or starts. So,
The back and forth movement of the seat portion 2 is prevented.

The above-described configuration may be arranged symmetrically on both sides of the front seat A, that is, the left and right pair of front legs 13, the front link 10, the rear link 36, and the rear legs 33 may be arranged on the frame 14, but only on the aisle side of the vehicle. In preparation for this, the leg on the window side may have the conventional configuration shown in FIG.

Generally, the seat portion 2 is configured such that the rear side thereof is inclined diagonally downward in order to improve the sitting comfort. , a step will be created between the seat portion 2 of the front seat and the seat portion 22 of the rear seat.

In order to create a continuous sloping surface between the front and rear seats without such a difference in level, the upper half of the link 10 should be bent forward as shown in Figure 4. good. When the lower half of the link 10 is tilted backward by an angle α from the normal state where it is tilted forward by an angle α about the pin 9, the seat portion 2
height is increased, and the rear legs 33 do not float off the floor 35.

[Effects of the invention] As described above, the present invention fixes the front legs to the seat of a movable seat arranged in front of a fixed seat, and connects a front link that can tilt forward and backward between it and the floor.
The bent part of the inverted L-shaped rear leg is connected to the lower end of a short rear link that is connected parallel to the front link to the seat, and the arm of the rear leg is connected to the middle part of the front link, so that the rear leg can move. Because it is configured so that it does not protrude to the rear,
The hind legs are not connected to the floor but are stably supported and can translate back and forth.

The conventional long bracket that juts out from the rear of the front movable seat is no longer needed, so the passenger does not trip when entering or exiting the fixed seat at the rear.
