Abstract
Abstract A seat pad support (12) disclosed includes at least one strip (22,24) of generally flexible tape which is preferably of the pressure sensitive type extending laterally between elongated supports preferably embodied by wire torsion bar springs (16) that cooperatively support a foam pad on a seat frame (14), whereby the tape connection of the springs facilitates storage, handling, and assembly. In the preferred construction, two end strips (22,24) of the tape respectively connect end torsion bars (28,30) of the springs (16). Each end tape strip (22,24) is folded and bonded to itself and preferably includes recesses (46) associated with the torsion bars (28,30) connected thereby so as to facilitate connection of the springs to the frame. The pad support (12) has particular utility for supporting a foam cushion pad (52) and its springs (16) incorporate forward and rearward intermediate torsion bars (32',32") respectively positioned above and below the tape connected front and rear end torsion bars (28,30) to provide support for the cushion pad (52 ) at an upwardly extending front pad recess (56) and a downwardly extending rear pad projection (58). In an alternate embodiment, two intermediate tape springs (39) connect central intermediate torsion bars (32) of the springs (16).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
156 words
A support for a seat pad comprising: a plurality of metal torsion bar springs including torsion bars with opposite ends and including connecting portions extending between the ends of the torsion bars, each spring having a pair of end torsion bars adapted to be respectively connected to spaced portions of a seat frame such that the springs extend therebetween in a spaced relationship to each other in order to permit mounting of the seat pad on the frame, each spring also having at least one intermediate torsion bar located between the end torsion bars thereof, and two strips of adhesive tape one of which is folded to connect one set of end torsion bars of the springs and the other of which is folded to connect the other set of end torsion bars of the springs to provide a connection therebetween in order to facilitate storage, handling, and assembly of the support to the seat frame.
Claim 2
Dependent Claim
156 words
A support for a seat pad comprising: a plurality of metal torsion bar springs including torsion bars with opposite ends and including connecting portions extending between the ends of the torsion bars, each spring having a pair of end torsion bars adapted to be respectively connected to spaced portions of a seat frame such that the springs extend therebetween in a spaced relationship to each other in order to permit mounting of the seat pad on the frame, each spring also having at least one intermediate torsion bar located between the end torsion bars thereof, and two strips of adhesive tape one of which is folded to connect one set of end torsion bars of the springs and the other of which is folded to connect the other set of end torsion bars of the springs to provide a connection therebetween in order to facilitate storage, handling, and assembly of the support to the seat frame.
Claim 3
Dependent Claim
33 words
A support as in claim 1 wherein each folded strip of adhesive tape includes a recess at each end torsion bar connected thereto in order to facilitate connection thereof to the seat frame.
Claim 4
Dependent Claim
41 words
A support as in claim 1 further including two additional strips of the adhesive tape connecting intermediate torsion bars of the springs and bonded to each other from opposite sides of the springs at a location intermediate the end torsion bars.
Claim 5
Dependent Claim
215 words
A support for a foam seat pad comprising: a plurality of metal torsion bar springs including torsion bars with opposite ends and including connecting portions extending between the ends of the torsion bars and connected thereto by abrupt bends; each spring having an elongated shape and including a pair of end torsion bars adapted to be connected to spaced portions of a seat frame so as to extend therebetween in a spaced relationship to each other spring in order to permit mounting of a foam seat pad on the frame; each spring also including at least one intermediate torsion bar located between the end torsion bars thereof; two strips of pressure sensitive adhesive tape extending laterally with one strip of tape associated with one set of end torsion bars of the springs and with the other strip of tape associated with the other set of end torsion bars of the springs; each strip of tape being folded and bonded to itself in order to connect the associated set of end torsion bars; the strips of tape cooperating to facilitate storage, handling, and assembly of the support to the seat frame; and each strip of tape including a recess at each end torsion bar connected thereto so as to facilitate connection thereof to the seat frame.
Claim 6
Dependent Claim
