Description

[Detailed description of the invention] This invention relates to a safety device for a movable seat in a car, for example, in which a seat placed in the middle of a car in which seats are arranged in three rows can be converted to a forward-facing or rearward-facing position. It is something.

The movable seat used in the above-mentioned automobiles is designed so that the seat, which serves as the seat, moves in the front and rear directions of the vehicle while rocking inside the vehicle, and the backrest, which serves as the backrest, can be moved separately to the front and rear end positions of the seat. configured and locked at each position.

Conventionally, when the seat placed in the middle is moved from the front end position to the rear end position, the feet of the occupant in the rear seat may get caught between the moving body of the movable seat, such as the seat bracket, and the floor, resulting in injury. Otherwise, there was a risk that the rear part of the seat bracket would hit the rear seat occupant's opposite shin, causing pain.

In view of the above points, this invention solves this problem by using a safety device with a simple configuration.
An example of the configuration of this invention shown in the drawings will be described below.

In Fig. 1, 1 is a seat, 2 is a pair of seat base brackets fixed inside the bottom surface of the seat, 3 is a floor, 4 is a leg support bracket fixed on the floor, 5 is a front leg, and 6 is a rear leg. be.

The seat 1 has front and rear legs 5 and 6 attached between a seat base bracket 2 and a leg support bracket 4 in a link configuration connected by pins 7, 8, 9, and 10. It is said that it can be converted to the position with rocking.

Reference numeral 11 indicates a backrest, and 12 indicates support fittings attached to both sides of the backrest.
2 is pivotally connected to a support bracket 13 via a pivot 14, and this support bracket 13 and seat brackets 15 fixed on both outsides of the seat 1 are connected by two parallel links 16, 17, and the front and rear of the seat 1 are connected to each other. A backrest 11 is attached at the end position so as to be swingable. Reference numerals 18, 19, 20 and 21 are connection pins for the two parallel links 16 and 17.

A reclining mechanism 22 is disposed on the support bracket 13, and by rotating a handle 23 provided on the support bracket 12 forward (leftward in FIG. 1), the backrest 11 can be moved forward and backward about the pivot shaft 14. It is designed so that it can be raised and lowered, that is, reclined, to an appropriate position.

The front legs 5 and rear part 6 of the seat 1 are pentagonal plate-shaped links, and at the front and rear positions of the seat 1, one of the two lower sides 5a, 5b, 6a, and 6b is 5a, 6a or 5b, 6b are in contact with the leg support bracket 4 on the floor 3, and one of the upper sides 5c, 6c is in contact with the base bracket 2 of the seat 1 to stably support the seat 1. It's becoming like that.

In order to stably maintain the front and rear end positions of the seat 1, a lock lever 24 is pivotally connected to the seat base bracket 2, and correspondingly, lock pins 25 and 26 are provided on some of the front and rear legs 5 and 6. It is being

The lock lever 24 is biased by a spring (not shown) so as to engage the lock pins 25, 26 of the front legs 5 or the rear legs 6 at the front and rear end positions of the seat 1. 27, the lock can be released. That is, the walk-in cable 27
has one end locked to the lock lever 24, and the other end locked to a part of the support fitting 12 of the backrest 11, so that the lock is released in conjunction with the movement of tilting the backrest 11 forward. is being done.

The parallel links 16 and 17 of the backrest 11 are also provided with locking devices for locking at the front and rear end positions, but these are omitted in the drawings.

The conversion procedure for Sheet 1 is as follows.

In the solid line state in FIG. 1, the seat 1 is at the rear end position, and the occupant is seated facing forward.

To turn this rearward, first rotate the handle 23 forward to move the backrest 11 to the first position.
Move from state A to state B in the diagram. This results in
The seat 1 is unlocked via the walk-in cable 27. Then, seat 1 and backrest 11 are integrally connected to the front of the vehicle body (left side in Fig. 1).
The front and rear legs 5 and 6 are used to swing the robot and move it from state B to state C. In this state of C, only the backrest 11 is once erected to the state of D, and then the parallel link 1 of the backrest 11 is
6 and 17 are released to swing only the backrest 11 from the state D to the state E. This means that the seat 1 has been converted to a rearward facing position.

The operation for changing from the backward facing position to the forward facing position is performed in the reverse manner to the above.

In this case, when the seat 1 is moved from the front end position to the rear end position, the feet 29 of the occupant seated on the rear seat 28 are inserted under the seat bracket 15 due to the rocking motion. The support brackets 13 may hit the occupant's legs due to rearward movement.

Therefore, in this invention, a guard block 30 is provided at the bottom of the rear end of the seat bracket 15 of the seat 1, which is located between the bottom surface of the rear end of the seat bracket 15 and the floor surface, and which constantly moves in sliding contact with the floor surface. It is something.

The guard block 30 is shown in FIG. 1 in which a U-shaped bracket 32 is provided on a part of the seat bracket 15 and is pivoted by a pivot 31. if there is,
It can be attached to any member.

This block 30 is for forcibly retracting the feet 29 of the occupant in the rear seat 28 rearward when the seat 1 is moved to the rear end position. (Width in the vehicle width direction) may be approximately the same as the width of the seat 1, or may be provided separately in an interference area between the moving body of the seat 1 including the seat bracket 15 and both legs of the occupant in the rear seat 28.

The material of the block 30 is not limited, but in order to reduce the weight, as shown in FIG.
It is preferable to cover and mold a metal plate 30a, which serves as reinforcement and weight, with a pad 30b made of synthetic resin, and to expose a portion of the reinforcing metal plate 30a to form the pivot joint portion 30c.

Although the safety device of the present invention has been described with respect to a movable seat that is moved back and forth with rocking motion by the front and rear legs, it can also be applied to a movable seat that moves back and forth using a slide rail, or even a movable seat that is equipped with a vertical adjustment mechanism. can also be applied.

As explained above, this invention is a turning seat for an automobile in which the seat is arranged on a movable body that can move back and forth or up and down with respect to the floor. It is located between the lower surface of the rear end of the body and the floor surface and moves in constant sliding contact with the floor surface, and when moving from the front end position of the seat to the rear end position,
A guard block is installed that forces the legs of the rear seat occupant to move backwards, so when the seat is moved from the front end position to the rear end position, the legs of the rear seat occupant are forcibly moved backwards by the block. It is possible to evacuate and remove the toe from the moving body, avoid getting the toe caught by the moving object, and avoid being bruised on the opposite shin, etc., and it is safe and has a simple configuration, so it can be equipped at low cost. Can be done.
