Abstract
Abstract A seat slide mechanism whose rail (fixed to the floor of a vehicle for example) and slide (fixed to the underside of a seat) are movable relative to one another in order to adjust the position of said seat, the position of said seat thereafter being maintained by a catch lever which has a number of prongs which extend through a like number of holes in the rail, said catch lever being carried by the slide. One end of the catch lever is pivotally connected to the slide and the other end of the catch lever is pivotally connected to an operating handle, the plane which contains the said two pivot axes being as nearly in alignment with the holes in said rail as the construction of the seat slide mechanism permits.

Total Claims: 9
Claim 1
Independent Claim
294 words
A seat slide mechanism comprising a. a rail securable to a floor so as to be fixed thereto; b. a slide securable to a seat so as to be fixed thereto; c. means providing parallel track surfaces on said rail and means providing parallel track surfaces on said slide, the rail and the slide being so disposed that one of the track surfaces on said rail is in vertical register with one of the tRack surfaces on said slide and that the other of the track surfaces on said rail is in vertical register with the other of the track surfaces on said slide; d. two rollers in contact with said one track surfaces and spaced from one another longitudinally of said rail and said slide, and two additional rollers in contact with said other track surfaces and spaced from one another longitudinally of said rail and said slide; e. a catch lever having two ends and an intermediate portion; f. a catch lever operating handle having two ends; g. first means establishing a pivotal connection between said operating handle and said slide; h. a slot in said slide and second means extending through said slot and establishing a pivotal connection between corresponding one ends of said catch lever and said operating handle; i. third means establishing a pivotal connection between the other end of said catch lever and said slide; j. at least two prongs formed in said intermediate portion of said catch lever; k. a rack on said rail, said rack being engageable by said prongs to effect a releasable connection of the slide to the rail; l. spring means connected between said slide and said operating handle and tending at all times to urge said prongs into engagement with said rack.
