Seat cushion mounting arrangement

Claim 2

In a vehicle seat adapted to be mounted on a vehicle and including a generally vertical seat back, a seat cushion component having front and rear edges and laterally spaced sides, and a base component, an adjustable arrangement for mounting the seat cushion component on the base component, the mounting arrangement comprising: a keeper mounted on one of the components and having a plurality of elongated openings spaced along an axis parallel to the seat cushion component sides, the openings extending laterally with respect to said axis; a latch member mounted on the other component for pivotal movement between latching and nonlatching positions, the latch member including a latching portion that is aligned with the laterally extending orientation of the openings while in the nonlatching position so as to be movable through any one of the openings as the cushion component is positioned on top of the base component, the location of the forward edge of the seat cushion being adjustably determined by the particular opening through which the latch member moves, the latching portion of the latch member moving into an unaligned relationship with respect to the openings upon movement of the latch member to the latching position, the unaligned relationship of the latching portion and the particular opening that receives the latch member maintaining the cushion component on the base component in the associated adjusted position of the cushion component with respect to the seat back, and the latching portion having a component extending along said axis in the latching position to permit tilting movement of the seat cushion component on the base component.

Claim 3

A seat according to claim 1 wherein the keeper is mounted on the base component and the latch member is mounted on the seat cushion component.

Claim 4

A seat according to claim 2 wherein the keeper is provided by a flange of a support member that pivotally mounts the seat back.

Claim 5

A seat according to claim 2 wherein the latch member is encircled by a compressible washer that engages the keeper and compresses during tilting movement of the seat cushion component.

Claim 6

A seat according to claim 1 wherein the keeper openings are open ended at their outboard sides.

Claim 7

A seat according to claim 1 wherein the latch member pivots about a vertical axis and the latching portion thereof is oriented at about 45° with respect to the vertical.

Claim 8

A seat according to claim 1 wherein the mounting arrangement includes a keeper and latch member at each side of the seat.

Claim 9

A seat according to claim 1 wherein there are three openings in the keeper.

Claim 10

A seat according to claim 1 wherein the latch member is moved between the latching and nonlatching positions by a manually actuated handle.

Claim 11

A seat according to claim 1 wherein the latch member moves approximately 90° between the latching and nonlatching positions.

Claim 12

A seat according to claim 1 wherein the keeper and latch member are located adjacent the rear edge of the seat cushion component.

Claim 13

In a vehicle seat adapted to be mounted on a vehicle and including a generally vertical seat back, a seat cushion component having front and rear edges and laterally spaced sides and a base component, an adjustable arrangement for mounting the seat cushion component on the base component, the mounting arrangement comprising: a keeper mounted on the base component and having a plurality of elongated openings spaced along a horizontal axis parallel to the seat cushion component sides, the openings extending laterally with respect to said axis; a latch member mounted on the seat cushion component for pivotal movement about a vertical axis between latching and nonlatching positions, the latch member including a latching portion that is aligned with the laterally extending orientation of the openings while in the nonlatching position so as to be movable through any one of the openings as the cushion component is positioned on top of the base component, the location of the forward edge of the seat cushion being adjustably determined by the particular opening through which the latch member moves, the latching portion of the latch member moving into an unaligned relationship with respect to the openings upon movement of the latch member to the latching position, the unaligned relationship of the latching portion and the particular opening that receives the latch member maintaining the cushion component on the base component in the associated adjusted position of the cushion component with respect to the seat back, and the latching portion having a component extending along said horizontal axis in the latching position to permit tilting movement of the seat cushion component; and a handle for moving the latch member between the latching and unlatching positions.

Claim 14

In a vehicle seat adapted to be mounted on a vehicle and including a generally vertical seat back, a seat cushion component having front and rear edges and laterally spaced sides and a base component, an adjustable arrangement for mounting the seat cushion component on the base component, the mounting arrangement comprising: a keeper mounted on the base component and having a plurality of elongated openings spaced along a horizontal axis parallel to the seat cushion component sides, the openings extending laterally with respect to said axis; a latch member mounted on the seat cushion component for pivotal movement about a vertical axis between latching and nonlatching positions, the latch member including a latching portion that is aligned with the laterally extending orientation of the openings while in the nonlatching position so as to be movable through any one of the openings as the cushion component is positioned on top of the base component, the location of the forward edge of the seat cushion being adjustably determined by the particular opening through which the latch member moves, the latching portion of the latch member moving into an unaligned relationship with respect to the openings upon movement of the latch member to the latching position, the unaligned relationship of the latching portion and the particular opening that receives the latch member maintaining the cushion component on the base component in the associated adjusted position of the cushion component with respect to the seat back, and the latching portion having a component extending along said horizontal axis in the latching position to permit tilting movement of the seat cushion component; and a handle for moving the latch member between the latching and unlatching positions.

Claim 15

A seat as in claim 12 further including a tilt adjuster for tilting the seat cushion component on the base component.

Claim 16

A seat as in claim 13 wherein the tilt adjuster includes a pair of cams located between and engaged with the seat cushion and base components, a shaft fixedly connected to the cams, and a handle for rotating the shaft and hence the cams to tilt the seat cushion component on the base component about the latch member.
