ABSTRACT:
This application is based on and claims priority under 35 U.S.C. §119 with respect to Japanese Application No. 10(1998)-261803 filed on Sep. 16, 1998, the entire content of which is incorporated herein by reference.
FIELD OF THE INVENTION
The present invention generally relates to a vehicle seat. More particularly, the present invention pertains to a vehicle seat provided with a fixture mechanism for fixing between seat supporting members and seat frames.
BACKGROUND OF THE INVENTION
Unexamined Published Japanese Patent Application (Kokai) No. Hei 6-55961 discloses a seat device that includes a pair of lower rails fixed on a vehicle floor, a pair of upper rails which slide on the lower rails, and lower frames which are fixed with a seat cushion frame (or pan) and which are also fixed to the upper rails by bolts. On the seat assembly line, a floor side member unit which includes a lower rail and an upper rail are fixed by bolts with a seat side member which includes a lower arm.
In this known type of seat device, overlapping portions exist between the floor side member unit and the seat side member for purposes of effecting the bolt fixing. This inevitably increases the seat width dimensions. Also, the bolt fixing process adds time to the assembly process, and the parts management associated with the bolt and nut fixation brings about increased costs.
In light of the foregoing, a need exists for a seat device that is not susceptible to the same disadvantages and drawbacks as other known seat devices.
SUMMARY OF THE INVENTION
In light of the above, the present invention provides a vehicle seat device that includes a lower rail fixed on a vehicle floor, a seat supporting member slidably supported on the lower rail and possessing a flat portion at its front upper part and a flange extending inwardly at its rear part, and a seat cushion frame having horizontal flat portions. The horizontal flat portions are set on and spot-welded to the flat portion and the flange.
According to another aspect of the invention, a seat device mounted in a vehicle includes a lower rail fixed on a vehicle floor, a seat supporting member slidably supported on the lower rail and possessing a flange extending towards one side of the seat supporting member, and a seat cushion frame having a horizontal flat portion. The horizontal flat portion of the seat supporting member is set on and welded to the flange.
In accordance with a further aspect of the invention, a seat device mounted in a vehicle includes a lower rail fixed on a vehicle floor, a seat supporting member slidably supported on the lower rail and possessing a flange extending towards an outer side of the seat supporting member, with the flange being provided with a skirt portion possessing clips. A seat cushion frame is fixed to the seat supporting member and a seat pad is positioned on the seat cushion. The seat cushion cover is provided with elements that engage the clips on the skirt of the flange.
