  It is desirable to integrate the slide lever so that the rail cover always covers the front end portion of the door side fixed rail regardless of the seat adjustment position.

Hereinafter, a seat truck used for an automobile seat according to the present invention will be described based on a specific example specified and illustrated. FIGS. 1 to 4 show the present invention used for a driver seat of a passenger car. A specific example 10 of a seat track used for an automobile seat is shown, and the seat track 10 includes a slide mechanism 11 and a lock mechanism 12, and the seat of the driver seat 40 is provided on the slide mechanism 11. A structure in which the cushion 41 is assembled and incorporated in the driver seat 40 is employed. Specifically, the seat cushion 41 is assembled by assembling a pad (not shown) on the cushion frame 42 and covering it with a trim cover (not shown). Is assembled to the left and right movable rails 15 and 16 of the slide mechanism 11 by the cushion frame 42, and thus the seat track 10 is incorporated into the driver seat 40.

  The slide mechanism 11 is assembled with the left and right fixed rails 13 and 14 and the left and right movable rails 15 and 16 supported so as to be slidably fitted to the left and right fixed rails 13 and 14, and The left and right fixed rails 13, 14 are formed from steel plates into elongated cross-section channel rails and the left and right front floor brackets 17, 18 and left and right rear floor brackets 19, 20 It is normally installed on the floor, and its left and right movable rails 15 and 16 are formed into a long and narrow hat-shaped rail from a steel plate, and normally reciprocates back and forth corresponding to the left and right fixed rails 13 and 14. The locking mechanism 12 is unlocked by the slide lever 32 and is fixed to the left and right fixed rails 13 and 14. It is moved to the position of Yichun and is stuck in the lock mechanism 12 in its moved position on the fixed rail 13, 14 of the left and right.

More specifically, the lock mechanism 12 includes left and right lock hole rows 21 and 22 drilled at predetermined intervals in the length direction on the left and right fixed rails 13 and 14 at predetermined positions in the length direction. The left and right latches 23 and 24 supported by the left and right latch brackets 25 and 26 corresponding to the left and right movable rails 15 and 16 and the left and right latches 23 and 24 correspond to the left and right lock hole rows 21 and 22, respectively. The front end of the arm is welded by left and right lock springs (not shown) and an arched cross interlock rod 29, and the left and right latch brackets 25 and 26 move the slide mechanism 11 left and right. The left and right operation arms 27 and 28 supported so as to be swingable in the vertical direction corresponding to the rails 15 and 16 side, and the door side of the left and right operation arms 27 and 28. Rail cover 30 covers the door side front end portion of the fixed rail 13, 14 of the right and left of the slide mechanism 11 is welded to an end, and rail thereof
The cover 30 includes a slide lever 32 or the like that protrudes integrally to the front end side of the upper surface 31 of the cover 30.

  The rail cover 30 is set to a shape that always covers the front end portion of the door-side fixed rail 14 regardless of the seat adjustment position. In particular, the rail cover 30 is set to have a length that covers the front end portion of the door-side fixed rail 14 at the rearmost position of the slide mechanism 11.

  Therefore, in the seat track 10, the front end portion of the door side fixed rail 14 of the slide mechanism 11 is always covered by the rail cover 30 regardless of the seat adjustment position, and the rear slide of the driver seat 40 is performed. At the time, the feeling of harm caused by the exposure of the door-side fixed rail 14 and the unsightly appearance of the door-side fixed rail 14 can be avoided in advance, and the appearance quality is improved, and the slide lever 32 integrated with the rail cover 30 is obtained. Can be easily operated at low cost without changing the unlocking mechanism and unlocking operation, and the space under the seat cushion 41 can be effectively used as a storage space for placing an under box 50, a tray, etc. Productivity is enhanced.

  As will be apparent from the specific embodiments of the present invention described above with reference to the drawings, for those of ordinary skill in the art to which the present invention pertains, It is easily embodied in another embodiment that derives from the nature and the nature of the invention and is objectively recognized as having them inherent. Of course, the content of this invention corresponds to the problem of the invention (be recommend with) and is essential for the establishment of the invention.

  As understood from the above, in the seat track used for the automobile seat of the present invention, the locking mechanism is integrally connected to the front end side of the arm by the arched cross interlock rod, and the slide mechanism is movable left and right. The left and right operation arms supported to be swingable in the vertical direction corresponding to the rail side, and the front end of the left and right operation arms on the door side are integrally connected, and the left and right fixed rails of the slide mechanism Since the rail cover that covers the front end portion on the door side and the slide lever that protrudes integrally on the front end of the rail cover are included, in the seat track used in the automobile seat of the present invention, the rail lever The front end portion of the door-side fixed rail of the slide mechanism is obscured, and when the seat slides backward, the door-side fixed rail The appearance quality is improved by removing the sense of harm from the appearance and the unsightly appearance, and the slide lever with integrated rail and cover can be operated without changing the unlocking mechanism or unlocking operation. The space under the seat cushion can be effectively used as a storage space, and the merchantability of the seat is enhanced. As a result, it is very useful and practical for automobile seats.
