Abstract
Abstract A slide mechanism, particularly for a vehicle seat, comprises an upper channel having a base secured to the vehicle seat, and a lower channel having a base secured to the vehicle floor, and the channels have limbs which are shaped to interlock to resist separation of the channels; sets of rollers are preferred to be located between the channels and, under abnormal loading, the channel limbs are adapted to deform around the rollers.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
125 words
A slide mechanism comprising a first channel having a base adapted to be secured to a movable member, a second channel in sliding engagement with said first channel and having a base adapted to be secured to a stationary member, and central roller means between said channels and having convex end faces, one of said channEls having limbs which extend inwardly to bear on said convex faces and then outwardly to terminate in ends and provide a pair of recesses which are angled to open away from said other channel, and the other of said channels having limbs which provide abutment faces adjacent said ends of the recessforming limbs and then extend inwardly to enter said recesses and interlock to resist separation of said channels.
Claim 2
Dependent Claim
125 words
A slide mechanism comprising a first channel having a base adapted to be secured to a movable member, a second channel in sliding engagement with said first channel and having a base adapted to be secured to a stationary member, and central roller means between said channels and having convex end faces, one of said channEls having limbs which extend inwardly to bear on said convex faces and then outwardly to terminate in ends and provide a pair of recesses which are angled to open away from said other channel, and the other of said channels having limbs which provide abutment faces adjacent said ends of the recessforming limbs and then extend inwardly to enter said recesses and interlock to resist separation of said channels.
Claim 3
Dependent Claim
35 words
A slide mechanism as claimed in claim 1, in which said limbs of said other channel are angled outwardly before extending inwardly and entering said recesses to provide said abutment faces with correspondingly angled form.
Claim 4
Dependent Claim
46 words
A slide mechanism as claimed in claim 1, and further comprising side roller means between said limbs of said channels, and in which said channels are adapted to deform around said side rollers under abnormal load to effect direct contact between the limbs of said channels.
Claim 5
Dependent Claim
51 words
A slide mechanism as claimed in claim 3, in which said central roller means and said side roller means comprise a plurality of sets of roller elements, each set comprising a central roller having convex end faces, a pair of side rollers, and a cage interconnecting said central and side rollers.
Claim 6
Dependent Claim
49 words
A slide mechanism as claimed in claim 2, in which said limbs of said one channel have end lengths which provide outwardly angled races for said side roller means, and said limbs of said other channel have end lengths which provide complementary angled races for said side roller means.
Claim 7
Dependent Claim
20 words
A slide mechanism as claimed in claim 1, in which said central roller means comprise a plurality of spherical rollers.
Claim 8
Dependent Claim
31 words
A slide mechanism as claimed in claim 1, in which said central roller means comprise a plurality of rollers each of which comprises a waisted body and generally conical end faces.
Claim 9
Dependent Claim
20 words
A slide mechanism as claimed in claim 2, in which said side roller means comprise a plurality of cylindrical rollers.
