Slide for a vehicle seat

Claim 2

A fore and aft slide for a vehicle seal including relatively slidable inner and outer channels having tops and sides and rigid ball means disposed and rollable in tracks between the outer surfaces of the sides of the inner channel and the inner surfaces of the sides of the outer channel, the inner and outer channels being in contact in the absence of any vertical load on the seat, one of the channels being capable under a predetermined vertical load of deformation within the elastic modulus of the channel material to cause the channels to move out of contact with one another, there being a series of notches for a locking detent along one channel.

Claim 3

A fore and aft slide as claimed in claim 1, in which the channels have respective bearing surfaces which are closely spaced apart under the predetermined load but which make contact with each other along the length of the channels during the deformation under load in excess of the predetermined load.

Claim 4

A slide as claimed in claim 1 including fixing means for the channels in the tops of said channels in positions where there is no interference with the ball means.

Claim 5

A slide as claimed in claim 1 in which the ball means are in races defined by respective facing angles of the channels each defined by a vertical and a horizontal surface of one of the channels, the line of thrust through a ball from channel to channel being inclined to the horizontal and vertical.

Claim 6

A slide as claimed in claim 1 in which the ball means provide location between the channels in both horizontal and vertical directions.

Claim 7

A slide as claimed in claIm 1 including sliding interlayers disposed between surfaces of the channels to establish the contact in the absence of any vertical load on the seat.

Claim 8

A slide as claimed in claim 1 in which one of the channels has stops pressed into its side for cooperating with the ball means to define limiting positions of the slide.

Claim 9

A slide as claimed in claim 1 in which the series of notches are arranged along the full length of the side of one channel.

Claim 10

A slide as claimed in claim 1 including a releasable latch for locking the slide in a chosen position of adjustment and a pivot pin for the latch fixed to a side of one channel.

Claim 11

A slide as claimed in claim 1 in which the said one channel having the notches has a part of its side projecting beyond the ball means from the top, the notches being in that part of its side.

Claim 12

A slide as claimed in claim 1 including a surface on the other channel against which the detent can bear when engaged in one of the notches.

Claim 13

An adjustable seat fixing in combination with a vehicle seat comprising two adjustment assemblies each constituting one side of the fixing, each assembly having an individual operating part pivotally mounted thereon about an axis transverse to the fore and aft axis of the seat for releasing the assembly for adjustment and a common manually-operable release member in the form of a rigid cross bar extending transversely wholly between the assemblies below the front of the seat and secured at its respective ends to the respective operating parts through snap-on connections, and being capable of downward bodily movement below the seat for releasing movement of both operating parts.

Claim 14

An adjustable seat fixing in combination with a vehicle seat comprising two adjustment assemblies each constituting one side of the fixing, each assembly having an individual operating part pivotally mounted thereon about an axis transverse to the fore and aft axis of the seat for releasing the assembly for adjustment and a common manually-operable release member in the form of a rigid cross bar extending transversely wholly between the assemblies below the front of the seat and secured at its respective ends to the respective operating parts through snap-on connections, and being capable of downward bodily movement below the seat for releasing movement of both operating parts.

Claim 15

A seat fixing as claimed in claim 12 in which each adjustment assembly comprises two relatively slidable channels for permitting adjustment of the fore and aft position of the seat.

Claim 16

A seat fixing as claimed in claim 12 in which the ends of the release member and the operating parts are telescoped together, and respective springs extend through corresponding notches to latch them together.
