Abstract
Abstract A vehicle seat track assembly comprising a lower frame member secured to the vehicle floor, an upper frame member secured to the seat and slidably supported on the lower frame member for relative movement fore and aft of the vehicle and a seat position control member supported on the frame members for movement in transverse directions among three positions: a locked position, in which the seat position control member is secured to both of the frame members to prevent relative movement thereof, an indexing position, in which the seat position control member is locked to the upper frame member but movable relative to the lower frame member so that the seat can be adjusted to discrete positions according to the desire of the user, and a slide position, in which the seat position control member is locked to the lower frame member but not to the upper frame member so that the seat can be slid forwardly a specified distance to facilitate passenger access to the back seat and then rearwardly to the previously adjusted position.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
368 words
A seat track assembly comprising an upper frame member adapted to be secured to a vehicle seat, a lower frame member adapted to be secured to the vehicle floor, said upper frame member being supported on said lower frame member for relative movement fore and aft of the vehicle, a first bracket on said upper frame member having a slot formed therein and an opening at one end of said slot, a second bracket on said lower frame member having a slot formed therein and a plurality of longitudinally spaced openings along said slot, said openings in said brackets having diameters substantially greater than the width of said slots, and a seat position control member supported on said frame members for movement in transverse directions between a locked position in which said seat position control member is secured to both said upper and lower frame members to prevent relative movement thereof, an indexing position in which said seat position control member is secured to said upper frame member but not to said lower frame member for relative movement to discrete positions with respect to said lower frame member, and a slide position in which said seat position control member is secured to said bottom frame member but not to said top frame member for relative movement of said top frame member on said bottom frame member within specified limits, said seat position control member having large diameter sections and small diameter sections, said large diameter sections being adapted to fit into said openings but not said slots, so that when said seat position control member is in said locked position, large diameter sections are received into openings on both said first and second bracket member, when said seat position control member is in said indexing position, a large diameter section is received into the opening on said first bracket member and a small diameter section is received into said slot on said second bracket member, and when said seat position control member is in said slide position, a large diameter section is received into one of the openings on said second bracket member and a small diameter section is received into the slot on said first bracket member.
Claim 2
Dependent Claim
368 words
A seat track assembly comprising an upper frame member adapted to be secured to a vehicle seat, a lower frame member adapted to be secured to the vehicle floor, said upper frame member being supported on said lower frame member for relative movement fore and aft of the vehicle, a first bracket on said upper frame member having a slot formed therein and an opening at one end of said slot, a second bracket on said lower frame member having a slot formed therein and a plurality of longitudinally spaced openings along said slot, said openings in said brackets having diameters substantially greater than the width of said slots, and a seat position control member supported on said frame members for movement in transverse directions between a locked position in which said seat position control member is secured to both said upper and lower frame members to prevent relative movement thereof, an indexing position in which said seat position control member is secured to said upper frame member but not to said lower frame member for relative movement to discrete positions with respect to said lower frame member, and a slide position in which said seat position control member is secured to said bottom frame member but not to said top frame member for relative movement of said top frame member on said bottom frame member within specified limits, said seat position control member having large diameter sections and small diameter sections, said large diameter sections being adapted to fit into said openings but not said slots, so that when said seat position control member is in said locked position, large diameter sections are received into openings on both said first and second bracket member, when said seat position control member is in said indexing position, a large diameter section is received into the opening on said first bracket member and a small diameter section is received into said slot on said second bracket member, and when said seat position control member is in said slide position, a large diameter section is received into one of the openings on said second bracket member and a small diameter section is received into the slot on said first bracket member.
Claim 3
Dependent Claim
119 words
The seat track assembly according to claim 1, wherein each of said upper and lower frame members has a side wall provided with a plurality of longitudinally spaced openings so that when said seat position control member is in said locked position a large diameter section is received into one of the openings on each of said upper and lower side walls, when said seat position control member is in said indexing position a large diameter section is received into one of the openings on said upper frame side wall, and when said seat position control member is in said slide position a large diameter section is received into one of the openings on said lower frame side wall.
Claim 4
Dependent Claim
53 words
The seat track assembly according to claim 2, further including means for moving said seat position control member in transverse directions comprising a cam member pivotally mounted on said upper frame member for movement about a vertical axis, said cam member having an end portion adapted to engage said seat position control member.
Claim 5
Dependent Claim
74 words
The seat track assembly according to claim 3, further including an abutment member secured to said upper frame member operable to abut said seat position control member and thereby prevent said seat position control member from moving into said slide position, and means connecting said abutment member to the vehicle seat back so that when said seat back is tilted forward, said abutment member is removed from abutment with said seat position control member.
Claim 6
Dependent Claim
29 words
The seat track assembly according to claim 3, further including spring means operable to urge said cam member and thus said seat position control member toward said locked position.
