The seat belt assembly includes a bracket, first and second guide members, a seat belt, a seat belt reel, and first and second portions of a buckle. The bracket is mounted to the headrest frame and the first guide member is mounted to the bracket. The second guide member, seat belt reel, and second portion of the buckle are mounted to the frame. The seat belt has a first end spooled into the seat belt reel. The seat belt extends up from the seat belt reel and is then threaded through the first and second guide members and the first buckle member. A second end of the belt is mounted to the frame. The first portion of the buckle is slidably mounted to the seat belt.

Abstract: A seat assembly includes a support structure supporting a layer of cushioning material. The support structure comprises a base, a pair of web supports mounted to the base with fasteners, a pair of connector bars interconnecting the web supports, and a web of fabric material extending between the connector bars. Engaging members are joined to the web and include hook portions that facilitate interconnecting the web with the connector bars. The layer of cushioning material is supported by the web.

Abstract: A vehicle seat for use in supporting a person wearing a self-contained breathing apparatus, the vehicle seat comprising: a frame; a seat cushion supported by the frame; a seat back assembly supported by the frame, the seat back assembly including a pair of spaced apart seat back members, the seat back members being spaced apart so as to house a self-contained breathing apparatus therebetween; a bracket mounted between and rearwardly of the spaced apart seat back members, the bracket being adapted to house a self-contained breathing apparatus; a headrest assembly supported by the frame above the seat back members, the headrest assembly including a pair of movable headrest members, the headrest members including a first headrest member hingedly connected to the frame for pivotal movement about a generally vertical axis between a first position wherein the first headrest member functions as a headrest and a forwardly pivoted position wherein the self-contained breathing apparatus housed between the seat back mem

Abstract: A vehicle seat support assembly for supporting a seat for vertical adjustable movement. The seat support assembly includes lower mounting rails which are fixed to the vehicle and an upper seat supporting frame to support a vehicle seat. Pivot links connected between the mounting rails and the upper seat supporting frame support the seat supporting frame for vertical movement with respect to the mounting rails. A locking rail locks the vertical position of the upper seat supporting frame with respect to the lower mounting rails. The locking rail includes a fixed second portion and a first portion fixed to the upper seat supporting frame which is movable forwardly and rearwardly with respect to the second portion of the locking rail.

Abstract: A vibration compensating vehicle seat suspension combines the vertical movement of the parallelogram suspension with the pivoting of the knee-pivot suspension. Three embodiments all include a horizontal pivot for pivoting of the seat, and a sublinkage for simultaneous vertical movement of the seat. A first embodiment includes a horizontal pivot and a vertical slide for sliding of the pivot. A rocking lever which rocks due to pivoting of the seat causes sliding of the pivot. A second preferred embodiment includes a horizontal pivot and a linkage for vertical movement of the front of the seat. A third preferred embodiment includes a horizontal pivot, a vertical slide, and a spring for biasing the pivot.

Abstract: A cam operated locking device for selectively locking or releasing an isolator frame for a seat that is slidable longitudinally on a support. The seat includes insolator frame has a locking recess therein. The locking device includes a U-bar housing affixed to a bracket on the support. There is a lever rod rotatable and slidable within the U-bar housing that is adapted to engage the recess in said isolator frame for locking the seat with respect to the bracket. Cam means including at least one pair of cam surfaces are formed on the U-bar housing. The lever rod carries a pin, which extends transversely within the U-bar housing and cooperates with the cam means. Spring means are disposed about the lever rod for biasing the lever rod into the recess in the seat frame. A handle is secured to the lever rod for rotating same. When the lever rod is in a first position on the cam means, the spring means will bias the lever rod into engagement with the recess.

Abstract: A collapsible seat for use in industrial machinery cabs or commercial vehicles. The seat is secured at one end to a hinge attached to a vertical support member. The other end of the seat is supported by foldable arms, and a flexible tension member interconnects a lever arm adjacent the seat and the foldable arms. Rotation of the lever arm causes the foldable arms to fold and the seat to collapse against the vertical support member.

Abstract: A toilet seat assembly includes a toilet seat mounted at its rear edge for swinging movement about a horizontal axis between a horizontal position and a raised position; and an operator-controlled device for selectively raising and lowering the seat, the device including an operator-actuated member movable between first and second positions a control member movable by the operator-actuated member to apply and remove raising torque to and from the seat in the first and second positions, respectively, and a resilient absorbing device connected to the control member for permitting movement of the control member upon forcible lowering of the seat when the control member is in its first position.

Abstract: An operator-controlled, toilet-seat lifting device applies a constant bias force, for example, by means of a helical spring, to the seat in a direction tending to raise the seat. The weight of the seat is sufficient to overcome the constant bias force so that the seat normally assumes a horizontal or down position. To raise the seat the user increases the bias force, for example, by depressing a foot-operated pedal connected to the bias means, so as to overcome the weight of the seat and cause the seat to swing upwardly. As the seat is held in raised position solely by bias force, forcible manual lowering of the seat when in its raised position does not damage any of the components.
