A long slide rail device for vehicle seat, which includes a temporary lock mechanism for temporarily locking an upper rail member fixed to the seat, at a predetermined temporary lock point, relative to a long lower rail member fixed in a floor of vehicle, so that the seat may be temporarily locked at that point, allowing its seat cushion to be folded upright to its seat back, before being displaced to a storage lock position. The temporary lock mechanism includes a female lock element (or female lock hole) provided in the lower rail member at the temporary lock point, and a male lock element so arranged at the upper rail element as to lie generally within the long lower rail member and movable for engagement with and disengagement from the female lock element. Thus, the structure of long slide rail device is simplified in structure and made small in sizes. Also, the temporary lock mechanism is provided with a connecting portion for allowing operative connection with other locking mechanism for locking the seat cushion or seat back at the temporary lock point in an interlocking relation therewith.

Long slide rail device for vehicle seat

A long slide rail for use in a vehicle seat, which comprises an elongated or long lower rail member, an upper rail member slidably fitted in the long lower rail member and a locking mechanism. In the locking mechanism, a swing linkage is provided, which extends alongside of the upper rail member and has one end connected to a lock plate slidably mounted in the same upper rail member. Thus, both swing linkage and lock plate are arranged within area of the upper rail member, avoiding projection therefrom, which lowers the seating surface of seat to a comfortable level.

Long slide rail for vehicle seat

A lumbar support device provided within a seat back of an automotive seat, which comprises a support wire having a lumbar support plate for supporting the lumbar part of an occupant on the seat, the support wire being mounted on the back frame of the seat back with such an arrangement that one end of the support wire is secured by a securing support member oriented in a direction intersecting that of a load applied to the support wire while the other end of the support wire is secured by another securing support member oriented in a direction intersecting that of an up-and-down adjustment of the support wire.
