Abstract
Abstract A seating structure which is adjustable and designed particularly for automobiles and the like. The seating structure includes a lower frame fixed to the floor of the vehicle and an upper seating frame situated over and spaced from the lower frame. An intermediate adjustable assembly is situated between the upper frame and the lower frame and is carried by the lower frame while being adjustable to adjust the elevation of the upper seating frame with respect to the lower frame. An adjustable spring assembly is operatively connected with the lower frame to provide for the latter a resilient resistance to a given load so that by adjusting the yieldability of the lower frame with respect to a given load it is possible for an individual to be very comfortably seated. At the same time the elevation of the seat can be adjusted independently of the adjustment for the particular load.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
203 words
Seating structure for automobiles and the like, comprising lower base frame means in the form of a parallelogram linkage, upper seat frame means situated over and spaced from said lower frame means, vertically adjustable intermediate means shiftable forwardly and rearwardly and carried by said lower base frame means and situated between the latter and said upper seat frame means to support the latter for independent elevational movement with respect to said lower base frame means, and adjustable spring means operatively connected only to said lower base frame means for yieldably supporting the parallelogram linkage of said lower base frame means to resist a given load on said upper seat frame means, said spring means comprising a spring leg shiftable at one end of a rigid base member of said lower base frame means within the range of an angle with respect to said parallelogram linkage for a given load along a slot formed in said lower base frame means to adjust for a particular load on said seating structure, whereby after adjustment of the spring means the intermediate means can be actuated to adjust the elevation of said seat frame means independently of the adjustment of said spring means and lower frame means.
Claim 2
Dependent Claim
203 words
Seating structure for automobiles and the like, comprising lower base frame means in the form of a parallelogram linkage, upper seat frame means situated over and spaced from said lower frame means, vertically adjustable intermediate means shiftable forwardly and rearwardly and carried by said lower base frame means and situated between the latter and said upper seat frame means to support the latter for independent elevational movement with respect to said lower base frame means, and adjustable spring means operatively connected only to said lower base frame means for yieldably supporting the parallelogram linkage of said lower base frame means to resist a given load on said upper seat frame means, said spring means comprising a spring leg shiftable at one end of a rigid base member of said lower base frame means within the range of an angle with respect to said parallelogram linkage for a given load along a slot formed in said lower base frame means to adjust for a particular load on said seating structure, whereby after adjustment of the spring means the intermediate means can be actuated to adjust the elevation of said seat frame means independently of the adjustment of said spring means and lower frame means.
Claim 3
Dependent Claim
92 words
The combination of claim 1 and wherein said intermediate means includes a carrying frame carried by said lower frame means, said seat frame means having four sides, and said intermediate means including four shear linkages respectively situated at said four sides of said upper seat frame means and operatively connected to the latter and to said carrying frame of said intermediate means, the latter also including an adjustable spindle extending vertically and operatively connected with said seat frame means for adjusting the elevation of the latter with respect to said carrying frame.
Claim 4
Dependent Claim
68 words
The combination of claim 2 and wherein said shear linkage means includes a pair of side shear linkage means and front and rear shear linkage means, and a laterally extending crank situated closely adjacent to one of said side linkage means and operatively connected to said spindle for turning the latter to regulate the elevation of said upper seat frame means with respect to said lower frame means.
Claim 5
Dependent Claim
136 words
The combination of claim 2 and wherein each shear linkage means includes a pair of levers crossing each other and pivotally connected to each other intermediate their ends, each pair of levers of each shear linkage means including one lever having one end pivotally connected with said lower carrying frame for movement about an axis which remains fixed with respect to said carrying frame and an opposite end pivotally connected to a carriage which is shiftable with respect to said upper seat frame means while the other lever of each shear linkage means has one end pivotally connected to said upper seat frame means for movement about an axis which does not move relative thereto while the other end of said other lever is pivotally connected with a carriage which is shiftable along said lower frame.
Claim 6
Dependent Claim
43 words
The combination of claim 2 and wherein said carrying frame is guided for movement with respect to said lower frame along rail-shaped guides, and releasable holding means for holding said carrying frame at a given position with respect to said lower frame means.
