Abstract

PROBLEM TO BE SOLVED: To prevent a striker from serving as a protrusion on a vehicle floor at the time of folding a seat by forming a connecting mechanism out of the striker and a lock tooth in a device provided with a sliding member which moves fore and aft is fitted at the leg of a rear seat through the connecting mechanism so that it can attached and removed freely. SOLUTION: The rear seat of a one-box car or the like is provided with a fixed rail 12 and a sliding member 15, and the fixed rail 12 is formed with its cross section of roughly L-shape which has an opening hole 13 on its top. A leg 21 of the rear seat is fitted through a connecting mechanism 23 at the sliding member 15 which moves forward and backward along the fixed rail 12 and has a roller 16 so that it may be attached and removed freely. In this case, the connecting mechanism 23 is constituted of a striker 25 which is fixed onto the sliding member 15 and a lock tooth 27 which is pivoted to the leg 21 of the rear seat and locked against the striker 25. It is thus possible to lower the position of the striker 25, and prevent the striker 25 from serving as a protrusion on a vehicle floor at the time of folding a seat.

2. Description of the Related Art In a conventional one-box car or the like,
Since both occupant loading and luggage loading are used, an average number of seats and luggage loading space are provided. There are cases where a detachable seat is provided in places other than the driver's seat and the passenger seat, and cases where a movable seat is provided.

[0003] When there is a lot of luggage, the seat provided with a detachable seat is removed, and the seat provided with a movable seat is moved forward to secure a luggage space. Such a seat apparatus is disclosed in Japanese Utility Model Laid-Open No. 4-131533 and Japanese Utility Model Publication No.
No. 11226 is known.

Further, as shown in FIGS. 5 (a) and 5 (b), in the conventional seat slide device 1, a fixed U-shaped member having an opening 3 at the upper part behind the front of the vehicle floor is provided. A rail 2 is provided, and a sliding member 5 having a roller 6 that moves back and forth along the fixed rail 2 is provided. The sliding member 5 is detachably attached to a leg portion 7 of a rear seat via a connecting mechanism 8. Installed.

The connecting mechanism 8 of the conventional seat slide device 1
Is a reverse U-shaped striker 9 provided obliquely upward on the rear end of the sliding member 5 and the leg portion 7 of the rear seat.
And a lock tooth 10 which is pivotally supported on the striker 9 and is locked to the striker 9.

[0006]

However, in the conventional seat slide device, the lock tooth cannot be easily locked to the striker unless the striker position of the connecting mechanism is formed high, and the striker position is formed high. In addition, when the seat is folded, it becomes a protrusion on the vehicle floor surface, and when the striker position is high, the position of the lock tooth also becomes high, and the height of the seat cannot be lowered.

The object of the present invention is to make the striker position of the connecting mechanism low so that the striker of the connecting mechanism does not become a protrusion on the vehicle floor when the seat is folded, and the seat height can be lowered. Provided is a vehicle seat slide device capable of performing locking work of a lock tooth easily and quickly, preventing looseness of a connecting mechanism, and further forming a narrow opening of a fixed rail to prevent intrusion of dust and the like. To do.
