Abstract
Abstract An adjustable seat assembly including a base, a seat frame and means for independently adjusting the vertical elevation of the front and rear portions of the seat frame relative to the base, including on each side of the assembly a pair of links which are pivotally connected between the base and the front and the rear of the frame for rotation between various angular positions to determine the vertical elevation between the front and rear of the seat frame and the base. Each link has connected thereto a latch member which is longitudinally displaced in accordance with the pivotal movement of the associated link. The frame carries catch means including horizontal portions having a plurality of longitudinally spaced slots which are selectively engaged by the respective latch members. A spring biases the latch members into the slots. An actuator means in the form of a manually operated handle is employed to selectively disengage either of the latch members from the catch means thereby to permit independent elevation of the front or rear of the seat frame relative to the base. The rear elevation adjustment is spring assisted.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
230 words
Apparatus for selectively and independently varying the height of the front and rear of a seat assembly relative to a support surface comprising: a base; a frame; first and second pairs of links pivotally connecting the front and rear, respectively, of the frame to the base and pivotally rotatable to permit independent elevation of the front and rear relative to the base; first and second pairs of latch members connected to the first and second pairs of links, respectively, and being longitudinally and oppositely displaceable by the links; catch means on each side of the frame and engageable with the respective pairs latch members for preventing longitudinal displacement thereof; and actuator means on each side of the frame for selectively disengaging the pairs of latch members from the catch means; each of said latch members including a first portion connected to the associated link and a second portion terminating in a vertical dog, the catch means including first and second pluralities of longitudinally spaced slots for receiving the dogs of the first and second latch members, spring means on each side of the frame for biasing the first and second pairs of latch members into engagement with the catch means and including for each of said spring means a flat, resilient band extending longitudinally in opposite Directions from a fixed center over and engaging the first and second latch members.
Claim 2
Dependent Claim
230 words
Apparatus for selectively and independently varying the height of the front and rear of a seat assembly relative to a support surface comprising: a base; a frame; first and second pairs of links pivotally connecting the front and rear, respectively, of the frame to the base and pivotally rotatable to permit independent elevation of the front and rear relative to the base; first and second pairs of latch members connected to the first and second pairs of links, respectively, and being longitudinally and oppositely displaceable by the links; catch means on each side of the frame and engageable with the respective pairs latch members for preventing longitudinal displacement thereof; and actuator means on each side of the frame for selectively disengaging the pairs of latch members from the catch means; each of said latch members including a first portion connected to the associated link and a second portion terminating in a vertical dog, the catch means including first and second pluralities of longitudinally spaced slots for receiving the dogs of the first and second latch members, spring means on each side of the frame for biasing the first and second pairs of latch members into engagement with the catch means and including for each of said spring means a flat, resilient band extending longitudinally in opposite Directions from a fixed center over and engaging the first and second latch members.
Claim 3
Dependent Claim
22 words
Apparatus as defined in claim 1 including a pair of additional links pivotally connecting the first pair of links to the base.
Claim 4
Dependent Claim
20 words
Apparatus as defined in claim 1 including track means for permitting longitudinal displacement of the base relative to the surface.
Claim 5
Dependent Claim
28 words
Apparatus as defined in claim 1 including means one the sides of the frame for limiting the longitudinal travel of the first and second pairs of latch members.
Claim 6
Dependent Claim
25 words
Apparatus as defined in claim 1 including first and second cross members connected between the links of the first and second pairs of links respectively.
Claim 7
Dependent Claim
61 words
Apparatus as defined in claim 1 wherein the actuator means includes adjacent each side portion a pivotal lifter extending longitudinally from a central pivotal point under and in engagement with a latch member of the first and second pairs of latch members, and means for selectively pivoting the lifters in synchronism to lift one or the other of the latch members.
Claim 8
Dependent Claim
52 words
Apparatus as defined in claim 6 wherein each of the catch means comprises an elongated rigid member secured to the frame and having a pair of longitudinally spaced horizontal plate portions, each of the plate portions having a plurality of longitudinally spaced slots therein for receiving the latch members in engagement therewith.
Claim 9
Dependent Claim
42 words
Apparatus as defined in claim 7 wherein the rigid members each includes a central horizontal portion, said spring means being centrally connected to the central horizontal portion and extending longitudinally in opposite directions therefrom to overly each of the spaced horizontal tabs.
