Description

[Detailed Description of the Invention] The present invention mainly relates to a locking mechanism for a forward-folding seat installed in an automobile.

As shown in FIG. 1, this type of forward-folding seat 10 includes a leg portion 1 that can be folded forward with its front edge as an axis 4, a seat portion 2 installed on the leg portion 1, and a seat portion 2 that can be folded into the seat portion 2. When the seat 10 is in use, a hook-shaped lock 5 extending from the rear of the leg 1 engages with an engaging part such as a striker 6 on the floor of the vehicle to prevent it from tipping forward. Seat 1
0 When not in use, the backrest portion 3
The space created by folding the seat 10 and then folding the seat 10 forward via the legs 1 is used as a luggage compartment or the like. However, in the conventional configuration described above, even when the seat 10 is tilted forward, the locks 5 protrude from the legs 1 as shown in FIG. There was a problem in that not only objects but also luggage etc. could come into contact with the lock 5 and be damaged.

The present invention aims to solve the above-mentioned conventional problems, and its main feature is to store the lock in the leg portion when the seat is tilted forward.

The present invention will be explained with reference to an embodiment shown in FIG. is penetrated, and the tip of the shaft 4 is fitted with a washer 41,
It is fixed with a nut 42. Thus leg 1 is axis 4
A hook-shaped lock 5 is extended from a hole 1A on the rear lower surface of the leg 1, and the lock 5 is fixed to a shaft 5A passing through the leg 1 with a pin 51. The shaft 5A has pins 51 at both ends.
A, 51A fixed to the leg 1, and the shaft 5
At the outer end of A is a lever 5 for releasing the lock 5.
C is installed. A lever 4B is attached to the middle part of the shaft 4 and fixed by a pin 41B, and a lever 5B is similarly fixed to the middle part of the shaft 5A. A protrusion 51B is further extended from the lever 5B, and a spring 5D is passed between the protrusion 51B and the lock 5. One end of the spring 5D passes through the hole groove 52 of the lock 5, and the other end is inserted into the protrusion. Press the rod 51B. Thus, the lock 5 is biased by the spring 5D in the direction of protruding from the hole 1A of the leg 1. Furthermore, the levers 4B and 5B are connected by a rod 7.

In the above configuration, when the seat 10 is used, the lock 5 is engaged with the striker 6 on the floor F side as shown in FIG. 5, but when the seat 10 is not used, the lock 5 is engaged with the striker 6 as shown in FIGS. The backrest part 3 is folded, the engagement between the lock 5 and the striker 6 on the floor F side is released by the lever 5B, and then the seat 10 is tilted forward via the leg part 1. Even if it is tilted forward, the lever 4B is fixed to the shaft 4 and does not move as shown in FIG. The lock 5 is housed in the leg 1 via the shaft 5A. When the seat 10 is put back into use, the lock 5 protrudes from the hole 1A of the leg 1 and engages the striker 6 due to the elasticity of the spring 5D.

The present invention is not limited to the above embodiments, and for example, the shaft 5A of the lock 5 can be connected to the backrest 3.
The lock and the striker may be disengaged from each other when the backrest 3 is folded, and the lock may be stored in the leg 1. good.

Since the present invention has the above configuration, when the backrest part is folded and the seat is folded forward, the lock that should be engaged with the engaging part on the floor side is stored in the leg part and the seat is folded forward. The resulting space is enlarged accordingly, and the appearance is also favorable, and there is no possibility that luggage or the like will come into contact with the lock and be damaged.
