摘要： A method of forming fabric for making foam-in-place molded articles such as preferably seat cushions. A film is secured to a frame and tacked by adhesive to a piece of fabric, not secured to the frame, that forms the outer covering of the seat cushion for permitting the fabric to move relative to the film during forming to enable fabrics which cannot stretch a considerable amount to be used. To form the fabric, the film and fabric are placed in a female mold and the film and fabric are drawn into a cavity of the mold and against a contoured surface in the cavity forming a recess in the film and fabric. To counteract compressive stresses in the fabric during forming, the frame can have one or more fabric tensioners that selectively apply tension to the fabric during forming. To mold the cushion, a foam is poured into the recess and allowed to cure until it hardens into a foam core and bonds with the film. Preferably, to fix the shape of the film and fabric to that of the contoured surface of the mold cavity to enable the foam to be poured into the recess without requiring the film and fabric to be supported by the mold, the adhesive, film and fabric are heated before forming to make them pliable and cooled after forming to fix their shape to substantially conform to that of the contoured surface of the mold cavity.

摘要： A concealed quick attach and detach mechanism for releasably installing and automatically locking a seat against lateral movement on a vehicle of the type having spaced apart first and second cantilever supports which terminate in first and second laterally spaced free ends. The mechanism includes a seat pan having a housing that includes a concealed interior and an interior support axis and first and second spaced apart apertures in the pan housing aligned on the lateral support axis that open into the interior for slidably receiving the first and second supports therethrough, respectively, when the seat is installed on the vehicle. A deflectable first lock is provided in the seat pan interior in register with the support axis and laterally spaced from the first aperture. A biasing area is provided for normally maintaining the first lock in register with the support axis and for permitting the first lock to be deflected out of register with the support axis during attaching and detaching of the seat on the vehicle. A second lock is provided in the seat pan interior in register with the support axis and laterally spaced from the second aperture; and the first and second locks are spaced apart laterally from each other a distance that is substantially equal to the lateral spacing of the free ends of the cantilever supports on the vehicle on which the seat pan is to be mounted for automatic abutment against the free ends when the seat is installed to restrain the seat against lateral movement.

摘要： A seat suspension having a stationary support that can be mounted on a vehicle. An intermediate frame is mounted on the stationary support for vertical sliding movement relative thereto by a spring suspension. A seat support frame is mounted on the intermediate frame for upward or downward movement relative thereto. A ratchet assembly interconnects the seat support frame and the intermediate frame and includes ratchet members on one of the frames and a pawl member on the other of the frames. A pawl release, including a biasing spring and a pawl actuating member, is provided to allow the support frame to be moved from the lower to any intermediate upper position and create an impulse at each position without need to activate said activating member. The activating member is operative to selectively move the pawl to a nonengagement position.

摘要： A vehicle seat having a bladder with more than two inflatable chambers and an integral control flap, all of one piece, integral construction. To maximize inflatable volume of each chamber, each chamber preferably has a sidewall portion that is generally perpendicular. The control flap has passages in communication with the chambers and valving for selectively controlling inflation of the chambers. Valving preferably includes pinch valves having a generally T-shaped body with legs that pinch passages in the control flap to retain gas in a chamber and selectively inflate or deflate the chamber. The bladder is connected to a gas supply having a pump in communication with a reservoir for storing a charge of pressurized gas in the reservoir so that the pump need not immediately operate when gas is needed to inflate a chamber. To maintain a charge of gas in the reservoir, the gas supply preferably includes a pressure switch for energizing the pump when the reservoir pressure drops below a lower threshold and deenergizing the pump when pressure rises above an upper threshold. A preferred bladder has a chamber for cushioning the thighs of a seat occupant, a chamber for cushioning the buttocks and can have a chamber for providing lumbar support. A bladder of this invention can be assembled as part of a motorcycle seat having a bladder for the driver and a bladder for the passenger. The bladder also can be used in automotive and off road vehicle seating applications.

摘要： Methods for forming a strip of thermoplastic material by punch clamping are described. One method includes providing a clamping mold with i) a surface having at least one die space and ii) at least one clamp having at least one punch tip located in a punch body; providing a strip of thermoplastic material having a softening temperature and a melting temperature; heating the strip of thermoplastic material to a working temperature higher than the softening temperature and lower than the melting temperature; placing the strip of thermoplastic material in the clamping mold and against the surface and over the at least one die space; forming the strip of thermoplastic material by closing the at least one clamp so as to a) form the strip of thermoplastic material with the at least one clamp and b) pierce the strip of thermoplastic material with the at least one punch tip, in one step; cooling the strip of thermoplastic material to a removal temperature lower than the softening temperature; opening the at least one clamp; and removing the strip of thermoplastic material from the clamping mold. The methods provide advantages in that the time required to form the strip of thermoplastic material is reduced, the need for expensive injection molding equipment is obviated and the configuration of the resultant rings can be quickly modified to permit flexible manufacturing by simply changing the configuration of the clamping mold.

摘要： A seat suspension including a downstop slide element having an overall width that automatically adjusts to compensate for dimensional variations between relatively stationary and movable frame parts of the seat suspension due to manufacturing tolerances and wear. The downstop has first and second leaf members having spaced apart first and second top and bottom walls, front and rear walls, and inner and outer walls, respectively. A connecting member interconnects the leaf members to place the first and second inner walls in opposed confronting relation for movement toward and away from each other to form a longitudinally extending slide gap therebetween of variable width. A first biasing member is provided to normally urge the pair of leaf members apart. A first tapered portion is provided on the inner wall of at least one of the leaf members. A cam surface is provided on the front wall of at least one of the leaf members. A width adjuster is positioned in the slide gap between the confronting walls and includes a second tapered portion in face-to-face sliding engagement with the first tapered portion and a cam follower in contact with the front wall cam surface. A second biasing member is provided to normally bias the width adjuster to move the respective tapered portions relative to each other in a direction to cause the gap to widen and increase the overall width of the downstop slide element as required to compensate for dimensional differences between the parts due to tolerances and wear and provide lateral stability to the seat suspension.
