Abstract

Abstract The present invention provides, in a preferred embodiment, a vehicle seat adjuster particularly suitable for the middle or forward seating of a three-row van or minivan type vehicle. The seat adjuster may be provided with a master-slave latch arrangement allowing adjustment by the vehicle seat occupant by manipulating a rod extending toward the front of the vehicle seat adjuster or by a vehicle occupant seated rearwardly manipulating a second rod extending toward the rearward end of the vehicle seat adjuster. Although particularly useful in van-type vehicles, this seat adjuster may also be used in conventional passenger vehicles. The seat adjuster has two latches which are moved to a nonengaged or release position by manipulation of a slidably mounted roller which is displaced by a rod to tension a cable connected to both of the latches.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 226 words
A manual vehicle seat adjuster, the adjuster comprising: a pair of generally parallel spaced floor channels; a series of notches fixed with respect to each floor channel; a pair of seat channels for mounting a vehicle seat, one of the seat channels being slidably mounted on each respective floor channel; a latch connected to each seat channel, the latch being mounted for relative movement with respect to the seat channel and being biased to a locked position engaging the notches fixed with respect to the floor channel locking the position of the seat channel with respect to the floor channel, and the latch having a release position removed from engagement with the notches fixed with respect to the floor channel, allowing adjustment of the seat channel with respect to the floor channel; an extension member connected to at least one of the seat channels, the extension member having a slot; a cable tensionally associated with both latches; at least one pin connected to the extension member, the pin having a rotational axis relative with respect to the extension member, the pin rotational axis also being slidable in the extension member slot, and the pin being in contact with the cable; and a rod for displacing the pin within the slot of the extension member, thereby tensioning the cable and moving both latches to a release position.
Claim 2
Dependent Claim 226 words
A manual vehicle seat adjuster, the adjuster comprising: a pair of generally parallel spaced floor channels; a series of notches fixed with respect to each floor channel; a pair of seat channels for mounting a vehicle seat, one of the seat channels being slidably mounted on each respective floor channel; a latch connected to each seat channel, the latch being mounted for relative movement with respect to the seat channel and being biased to a locked position engaging the notches fixed with respect to the floor channel locking the position of the seat channel with respect to the floor channel, and the latch having a release position removed from engagement with the notches fixed with respect to the floor channel, allowing adjustment of the seat channel with respect to the floor channel; an extension member connected to at least one of the seat channels, the extension member having a slot; a cable tensionally associated with both latches; at least one pin connected to the extension member, the pin having a rotational axis relative with respect to the extension member, the pin rotational axis also being slidable in the extension member slot, and the pin being in contact with the cable; and a rod for displacing the pin within the slot of the extension member, thereby tensioning the cable and moving both latches to a release position.
Claim 3
Dependent Claim 67 words
A seat adjuster as described in claim 1 having two rods, one rod being accessible from a front end of the seat adjuster and a second rod being accessible from a rear end of the seat adjuster, each rod being operatively associated with a pin relatively mounted on the two seat channels allowing the seat adjuster to be actuated from the front end or the rear end.
Claim 4
Dependent Claim 21 words
A seat adjuster as described in claim 1 having a latch mounted for linear movement with respect to the seat channel.
Claim 5
Dependent Claim 23 words
A seat adjuster as described in claim 2 wherein the rods displace the respective pins in generally opposite directions to release the latches.
Claim 6
Dependent Claim 27 words
A seat adjuster as described in claim 1 further including a secondary rotational pin contacting the cable having a fixed axis with respect to the seat channel.
Claim 7
Dependent Claim 198 words
A manual vehicle seat adjuster, the adjuster comprising: a pair of generally parallel spaced floor channels; a series of notches fixed with respect to each floor channel; a pair of seat channels for mounting a vehicle seat, one of the seat channels being slidably mounted on each respective floor channel; a latch connected to each seat channel, the latch being mounted for relative movement with respect to the seat channel and being biased to a locked position engaging the notches fixed with respect to the floor channel locking the position of the seat channel with respect to the floor channel, and the latch having a release position removed from engagement with the notches fixed with respect to the floor channel, allowing adjustment of the seat channel with respect to the floor channel; a force transmission member associated with both latches; a first rod accessible by a seat occupant operatively associated with the force transmission member for tensioning the cable and moving both latches to a release position; and a second rod accessible from the rear of the seat adjuster operatively associated with the force transmission member for tensioning the cable and moving both latches to a released position.
Claim 8
Dependent Claim 198 words
A manual vehicle seat adjuster, the adjuster comprising: a pair of generally parallel spaced floor channels; a series of notches fixed with respect to each floor channel; a pair of seat channels for mounting a vehicle seat, one of the seat channels being slidably mounted on each respective floor channel; a latch connected to each seat channel, the latch being mounted for relative movement with respect to the seat channel and being biased to a locked position engaging the notches fixed with respect to the floor channel locking the position of the seat channel with respect to the floor channel, and the latch having a release position removed from engagement with the notches fixed with respect to the floor channel, allowing adjustment of the seat channel with respect to the floor channel; a force transmission member associated with both latches; a first rod accessible by a seat occupant operatively associated with the force transmission member for tensioning the cable and moving both latches to a release position; and a second rod accessible from the rear of the seat adjuster operatively associated with the force transmission member for tensioning the cable and moving both latches to a released position.
