Abstract

Ends of each supporting pin are projected to both sides of each link plate. Each supporting shaft is fixed by welding to each link plate at a position near one end side of the plate. A pipe-like connecting shaft is axis-aligned to and fitted on an end portion of the supporting pin which projects inward from each link plate, so as to be supported between link plates. An end portion of the supporting pin which projects outward from each link plate is passed through a side frame section and fixedly riveted over. Further, each link plate is fixed by welding to both ends of the connecting shaft, and a link base frame is assembled between side frame sections.

Claims

1. A height adjusting device for adjusting a height of a vehicle seat, said vehicle seat including a seat cushion frame supported through first and second pairs of spaced apart brackets, said seat cushion frame having a pair of first and second spaced apart side frame sections, said height adjusting device comprising two pairs of forward and rearward linkage members, said forward linkage members being bridged between first portions of said side frame sections and said first pair of said spaced apart brackets, said rearward linkage members being bridged between second portions of said side frame sections and said second pair of said spaced apart brackets, a connecting shaft rotatably supported to said side frame sections, said rearward linkage members being supported by said connecting shaft, and an operating knob attached to said first side frame section for causing said forward and rearward linkage members to be actuated, thereby causing said vehicle seat to be vertically moved, characterised in that said height adjusting device includes supporting pins having first end portions and second end portions, said first end portions of said supporting pins being penetrated through said rearward linkage members, welded to said rearward linkage members and fitted in both ends of said connecting shaft, said second end portions of said supporting pins being penetrated through said spaced apart side frame sections and riveted over, whereby said connecting shaft is rotatably supported to said side frame sections, and said rearward linkage members being welded to said connecting shaft.
