Abstract
Abstract A resilient mounting for a reclining seat, the mounting including a first member to be secured to a supporting base for the seat, a second member to be secured to the seat and which is pivotally connected to the first member, and a torsion bar which forms the pivot for the two members and which provides a return bias when one of the members is tilted relative to the other.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
165 words
A resilient mounting for a reclining seat, said mounting comprising a first member to be secured to a supporting base for the seat, a second member to be secured to the seat and a torsion bar pivotally connecting the second member to the first member, said torsion bar forming a pivot for the two members and providing a return bias when one of the members is tilted relative to the other, said torsion bar having a first bent over free end section which reacts against the first member, a second bent over free end section which reacts against the second member and an elongate rectilinear portion intermediate said free end sections which forms the pivot for the two members, aligned cradles on said first and second members which locate a portion of said elongate rectilinear portion of said torsion bar which forms the pivot, and retainers on said first and second members for rotatably retaining said elongate portion of the torsion bar in said cradles.
Claim 2
Dependent Claim
165 words
A resilient mounting for a reclining seat, said mounting comprising a first member to be secured to a supporting base for the seat, a second member to be secured to the seat and a torsion bar pivotally connecting the second member to the first member, said torsion bar forming a pivot for the two members and providing a return bias when one of the members is tilted relative to the other, said torsion bar having a first bent over free end section which reacts against the first member, a second bent over free end section which reacts against the second member and an elongate rectilinear portion intermediate said free end sections which forms the pivot for the two members, aligned cradles on said first and second members which locate a portion of said elongate rectilinear portion of said torsion bar which forms the pivot, and retainers on said first and second members for rotatably retaining said elongate portion of the torsion bar in said cradles.
Claim 3
Dependent Claim
34 words
A resilient mounting according to claim 1, in which the torsion bar comprises a metal bar which is bent to form a second elongate portion which extends generally alongside the first said elongate portion.
Claim 4
Dependent Claim
69 words
A resilient mounting according to claim 2, in which the first said elongate portion of the torsion bar has said first free-end section which extends substantially at right angle thereto and abuts a reaction means on the first member, and the second said elongate portion of the torsion bar has said second free-end section extending substantially at right angle thereto and which abuts reaction means on the second member.
Claim 5
Dependent Claim
48 words
A resilient mounting according to claim 3, in which the reaction means on the first member is a fixed surface on the first member and the reaction means on the second member is adjustable relative to the second member to enable the torsion bar to be torsionally pre-loaded.
Claim 6
Dependent Claim
41 words
A resilient mounting according to claim 3, in which the free-end section of the first said elongate portion of the torsion bar prior to assembly into the mounting is inclined to a common plane containing the remainder of the torsion bar.
Claim 7
Dependent Claim
84 words
A resilient mounting according to claim 1, in which the second member is in the form of an open top tray affixed to the bottom of the seat so that the seat covers the open top and said first member contained in said open top, said first member being accessible through an aperture in the bottom of the second member, said aperture being in alignment with a portion of the first member which is to be secured to the supporting base for the seat.
Claim 8
Dependent Claim
35 words
A resilient mounting according to claim 2, in which the metal bar forming the torsion bar is bent so that the resulting elongate first and second portions converge in the direction away from the bend.
Claim 9
Dependent Claim
63 words
A resilient mounting according to claim 1, in which the torsion bar comprises a metal bar which is bent to form an elongate portion which provides the pivot and two free-end sections which are substantially at right angles thereto, one of said free-end sections abutting reaction means on the first member and the other free-end section abutting reaction means on the second member.
Claim 10
Dependent Claim
44 words
A resilient mounting according to claim 8, in which the reaction means on the first member is adjustable relative to the first member to enable the torsion bar to be torsionally pre-loaded, and the reaction means on the second member is a fixed surface.
Claim 11
Dependent Claim
36 words
A resilient mounting according to claim 1, in which the cradles on the first and second members provide aligned bearing surfaces which engage the pivot-forming portion of the torsion bar over the majority of its length.
