Abstract
Abstract Springs and straps laterally and vertically buttress lateral buttock support wings of a motorcycle seat. The springs are flat and sinuous and extend slightly upward and outward from the seat pan to support the seat wings. Straps secure to the springs and pass inwardly from them through a hole in the pan to an anchor point for the straps underneath the pan. The length of the straps is adjustable to adjust the lateral distance between the springs in the wings and the response to force applied to the springs. The straps restrain the springs in their spreading under rider load. The looser the straps the more the springs deflect vertically and laterally under rider load.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
115 words
An improved motorcycle seat comprising: (a) a base; (b) a seat on the base including a seat bottom and a pair of lateral wings, the wings extending upwardly and laterally from the seat bottom; (c) spring means supporting each of the wings and resisting laterally outward and downward forces thereon, the spring means being attached to the base and having a free end above the base in each wing; and (d) strap means attached proximate the free ends of the spring means and anchored to the base about midway between the wings, the strap means passing above the spring means and below the seat bottom to provide direct support of the bottom and the wings.
Claim 2
Dependent Claim
115 words
An improved motorcycle seat comprising: (a) a base; (b) a seat on the base including a seat bottom and a pair of lateral wings, the wings extending upwardly and laterally from the seat bottom; (c) spring means supporting each of the wings and resisting laterally outward and downward forces thereon, the spring means being attached to the base and having a free end above the base in each wing; and (d) strap means attached proximate the free ends of the spring means and anchored to the base about midway between the wings, the strap means passing above the spring means and below the seat bottom to provide direct support of the bottom and the wings.
Claim 3
Dependent Claim
46 words
The improved motorcycle seat claimed in claim 1 including adjustment means for the straps to lengthen or shorten them, whereby the position of the spring means and the stiffness of the support system of the spring means and strap means can be varied by the adjustment.
Claim 4
Dependent Claim
31 words
The improved motorcycle seat claimed in claim 2 wherein the spring means comprise at least one flat spring extending continuously from within one lateral wing to within the other lateral wing.
Claim 5
Dependent Claim
20 words
The improved motorcycle seat claimed in claim 3 wherein the continuous spring attaches to the base by the strap means.
Claim 6
Dependent Claim
36 words
The improved motorcycle seat claimed in claim 4 wherein the spring is sinuous in form and has serially connected convolutions that lie across the axis of the spring that extends along the length of the spring.
Claim 7
Dependent Claim
37 words
The improved motorcycle seat claimed in claim 5 wherein the spring attaches to the base by the strap means passing through a convolution of the spring so that spring material of the convolution engages the strap means.
Claim 8
Dependent Claim
39 words
The improved motorcycle seat claimed in claim 3 wherein the strap means attach to the spring means such that a rider's load on the strap means forces the free ends of the spring towards each other and the rider.
Claim 9
Dependent Claim
150 words
An improved motorcycle seat of the type having a seat bottom, a wing on each side of the seat bottom extending laterally and upwardly from the seat bottom, a support base below the seat bottom, and cushion means forming a part of the wings and seat bottom for the comfort of a rider on the seat, the improvement comprising: (a) spring means supporting each of the wings laterally and vertically on the base and being attached to the base, the spring means having free ends spaced from and above the base; and (b) strap means attached to the spring means in each of the wings proximate the free ends thereof and extending above the spring means to about the centerline of the seat, the strap means being anchored to the base providing support for the seat bottom and lateral wings, and supporting the spring means against lateral and downward deflection.
Claim 10
Dependent Claim
150 words
An improved motorcycle seat of the type having a seat bottom, a wing on each side of the seat bottom extending laterally and upwardly from the seat bottom, a support base below the seat bottom, and cushion means forming a part of the wings and seat bottom for the comfort of a rider on the seat, the improvement comprising: (a) spring means supporting each of the wings laterally and vertically on the base and being attached to the base, the spring means having free ends spaced from and above the base; and (b) strap means attached to the spring means in each of the wings proximate the free ends thereof and extending above the spring means to about the centerline of the seat, the strap means being anchored to the base providing support for the seat bottom and lateral wings, and supporting the spring means against lateral and downward deflection.
Claim 11
Dependent Claim
52 words
The improved motorcycle seat claimed in claim 8 including adjustment means on the strap means to vary the length of the strap means, whereby to vary the resistance of the spring means and strap means to lateral and downward deflection and the contour of the wings with respect to the seat bottom.
Claim 12
Dependent Claim
25 words
The improved motorcycle seat claimed in claim 8 wherein the spring means is in the form of at least one sinuous and generally flat spring.
Claim 13
Dependent Claim
51 words
The improvement claimed in claim 9 wherein the spring means including at least two opposed, generally flat and sinuous form springs each of a plurality of convolutions, the springs being attached together at adjoining bights of the springs, and the strap means includes strap means for each of the spring means.
Claim 14
Dependent Claim
26 words
The improvement claimed in claim 11 wherein each of the springs extends continuously from within one of the wings to within the other of the wings.
Claim 15
Dependent Claim
48 words
The improvement claimed in claim 12 wherein the strap means attach to the springs such that a rider's load on the strap means forces the free ends of the springs towards each other and the rider, and the springs bow in the wings to present opposed, concave curves.
Claim 16
Dependent Claim
18 words
The improvement claimed in claim 13 wherein the strap means attach each of the springs to the base.
Claim 17
Dependent Claim
28 words
The improvement claimed in claim 14 wherein the strap means attach each of the springs to the base by engaging the sides of a convolution of the springs.
Claim 18
Dependent Claim
33 words
The improvement claimed in claim 15 wherein the adjustment means includes buckle means beneath the base with means on the buckle means to secure the straps to the base at their desired length.
Claim 19
Dependent Claim
21 words
The improvement claimed in claim 16 wherein the base is a pan adapted for attachment to the frame of a motorcycle.
Claim 20
Dependent Claim
52 words
The improved motorcycle seat claimed in claim 8 including adjustment means on the strap means to vary the length of the strap means, whereby to vary the resistance of the spring means and strap means to lateral and downward deflection and the contour of the wings with respect to the seat bottom.
