Next, the operation of the vehicle seat holding device of the present invention will be explained. A seat holding member 10 that supports and holds the seat 6 on a cross member 9 installed on a seat rail 8'' that is parallel to the longitudinal direction of the vehicle, and a locking member 12 that prevents the seat 6 from coming off are connected to the seat rail 8. Since they are arranged in parallel to each other in orthogonal directions, even if the seat 〇 bends in the front-rear direction as the seat is seated, the engagement state between the seat holding member 10 and the latching member 12 will not be affected. Therefore, the lock plate 13 does not fall out from the locking member 12. In addition, the hanging member 1
2 is attached to the lock play 1 by a predetermined distance in the direction in which the lock play 13 engages with the locking member 12 (to the right in FIG. , Even if the left side of the sheet 〇 bends in the left-right direction and sinks, the lock plays 1 to 13 move in the direction of being hooked to the hooking member ]2, so the hooking state becomes more secure, and they are less likely to come off. If the right side of the seat 6 sinks, the amount by which the lock plate 13 moves in the direction away from the latching member]-2 is extremely small, and the return spring 18 is biased to rotate in the latching direction. , they don't come off.

Furthermore, since the intermediate piece 12a of the latching member 12 is provided along the longitudinal direction of the vehicle, even if the seat 6 bends in the longitudinal direction, the latching state between the latching member 12 and the lock plate 13 is not affected. do not have.

Furthermore, when removing the seat 6, hold the seatron lever 14 by its handle 14b and keep it rotated clockwise in FIG. 4 against the urging force of the return spring 18, as described above. Since the sheet 6 can be held by placing the part of the hand holding the handle 14b, for example, the thumb, on the upper surface of the sheet 6, the sheet 6 can be removed with one hand and with a one-touch operation. becomes possible.

(Effects of the Invention) As detailed above, the vehicle seat holding device of the present invention has the following features:
A seat holding part that supports and holds the seat in a fixed position on a cross member installed on a seat rail parallel to the front-rear direction of the vehicle, and a latching member to which a latching body of the seat is latched to prevent the seat from coming off. are arranged in parallel with each other in a direction orthogonal to the seat rail.

Therefore, since the seat holding member and the locking member are arranged parallel to each other in the direction orthogonal to the seat rail on the cross member, even if the seat bends in the front-rear direction, the lock plate will not come off from the locking member, and the seat rail will not come off. It becomes possible to hold the sheet stably.
