Abstract:
A slide device for a vehicle seat, comprising:a C-shaped lower rail (2) including a bottom wall (21) extending widthwise of said lower rail (2), first and second side walls (22a, 22b) extending from respective opposite side edges of said bottom wall (21) in a direction perpendicular to said bottom wall (21), first and second top walls (23a, 23b) extending inwardly from respective top edges of said first and second side walls (22a, 22b) and terminating spaced a distance from each other, and first and second dependent walls (24a, 24b) extending towards said bottom wall (21) from respective edges of said first and second top walls (23a, 23b) and defining a space (26) therebetween;an upper rail (3) mounted on said lower rail (2) for sliding movement relative to said lower rail (2) and including an upright wall (3a, 31a, 32a) lying perpendicular to said lower rail (2), and a pair of first and second U-shaped walls (31b, 32b) branched from said upright wall (3a, 31a, 32a) and received in said lower rail (2),said first U-shaped wall (31b) including a vertical wall (31b.sub.1) extending from said upright wall (3a, 31a, 32a), a bottom wall (31b.sub.3) extending laterally outwardly towards said first side wall (22a) of said lower rail (2) from a lower edge of said vertical wall (31b.sub.1), and an upturned wall (31b.sub.2) extending in parallel with said vertical wall (31b.sub.1) from a side edge of said bottom wall (31b.sub.3),said first and second U-shaped walls (31b, 32b) being arranged so that said vertical wall (31b.sub.1) is located in said space (26) between said first and second dependent walls (24a, 24b) with said upturned wall (31b.sub.2) being located between said first dependent wall (24a) and said first side wall (22a) and with said second dependent wall (24b) being located within said second U-shaped wall (32b),said first dependent wall (24a) having a lower edge provided with a plurality of downwardly extending teeth (25),said vertical wall (31b.sub.1) having at least one aperture (35) shaped to define an upwardly extending inner tooth (33),said upturned wall (31b.sub.2) having at least one upwardly extending outer tooth (34);a slide lock means (4) having at least one plate (44) laterally extending through said aperture (35) in a direction perpendicular to said vertical wall (31b.sub.1) and provided with an opening (5) with which said inner and outer teeth (33, 34) of said vertical wall (31b.sub.1) and said upturned wall (31b.sub.2) are fitted so that said lock means (4) is moveable together with said lower rail (2),said lock means (4) being displaceable between a lower, unlock position at which said opening (5) of said plate (44) is disengaged with said teeth (25) of said first depending wall (24a) of said lower rail (2) to permit the longitudinal movement of said upper rail (3) relative to said lower rail (2) and an upper, lock position at which said opening (5) of said plate (44) is engaged with one of said teeth (25) of said first depending wall (24a) of said lower rail (2) to prevent the longitudinal movement of said upper rail (3) relative to said lower rail (2); andmeans (6, 7, 8, 9) for displacing said lock means (4) between said lock position and said unlock position.
