Abstract
A patient-type chair is provided which is capable of a gentle rocking motion and which comprises rigid armrests for ease of ingress and egress. The chair comprises a base having a pair of substantially rigid front legs. The legs extend vertically and then rearwardly in a substantially horizontal disposition to form rigid armrests. The chair further comprises a back attached to a seat, the seat being rearwardly cantilevered from points on the front legs which are below the armrests.
Claims36
A chair comprising:
- a. a rearwardly extending, substantially horizontal, downwardly deflecting seat means having a front and a rear for supporting a human body in a seated position;
- b. a pair of substantially rigid, substantially vertical front legs spaced apart from each other;
- c. a pair of substantially parallel, non-deflecting armrests disposed in spaced relation to one another, each armrest extending rearwardly from a respective one of the front legs;
- and
- d. structure means for cantilevering the seat means below the armrests from the front legs at the front of the seat means so that the seat means can provide a rocking motion that increases rearwardly while the seat means is non-downwardly deflecting at its front edge;
- wherein an individual seated upon the chair can support each of his arms upon one of the armrests so that an individual ingressing into and egressing from the chair can support his weight by pressing against the armrests with his hands, and
- wherein the front of the seat means and the front of the armrests are in substantially the same vertical plane for ease of ingres and egress.

A chair having a front and a rear and capable of a rocking motion, comprising:
- (a) a base comprising
- a pair of substantially rigid front legs extending upwardly in a generally vertical direction and then rearwardly in a substantially horizontal direction to form rigid armrests;
- (b) a substantially horizontal seat having a front and a rear;
- and
- (c) a back extending vertically above the seat;
- wherein the seat and the back are comprised of the two steel side members affixed in parallel relation by cross-connecting transverse bars and fabric stretched between the side members to form a sitting surface and a back rest,
- wherein the seat is cantilevered near its front to each of the front legs below the armrests so as to be non-downwardly deflecting at its front and downwardly deflecting at its rear to provide a rocking motion that increases rearwardly,
- wherein the seat deflects downwardly a distance between about 0.2 and about 0.5 inches when a 100 pound weight is placed on the seat at a distance about 12 inches rearwardly from the front of the seat,
- wherein the back is S-shaped and deflects horizontally in a rearward direction when a force of 50 pounds is applied horizontally and rearwardly to the back at a point about 12 inches below the seat, and
- wherein the front of the seat and the front of the armrests are in substantially the same vertical plane for ease of ingress and egress.

The chair as defined in claim 22 or 26, wherein the transverse bars are U-shaped and the back comprises a removable chair back that can be removed and replaced without disassembling the chair, the chair back comprising:
- (a) a cover defining an interior back volume having a forward side, a rearward side, a left side, a right side, an upper end and a lower end, wherein the cover has a lower edge opening across the length of the lower end and a transverse bar opening which, when the back is attached to the chair, is aligned with an upper one of the U-shaped transverse bars;
- (b) a back pad disposed wtihin the cover, the planar configuration of the back pad being substantially the same as the planar configuration of the interior back volume;
- (c) a lower end fastener for closing the lower edge opening;
- (d) a transverse bar opening fastener for closing the transverse bar opening except for a left gap at the left side of the transverse bar opening and a right gap at the right side of the transverse bar opening, wherein the left gap and the right gap have substantially the same diameter as the upper U-shaped transverse bar so that, when the chair back is in use with the transverse bar opening fastener closed, the upper U-shaped transverse bar protrudes out of the left gap and back into the right gap;
- (e) a forward seat liner affixed within the cover adjacent to and in parallel with the back pad;
- and
- (f) a rearward seat liner affixed within the cover adjacent to and in parallel with the rearward side of the cover;
- wherein the planar configuration of the forward seat liner and the rearward seat liner substantially the same as the planar configuration of the back pad.

A multiple seat chair comprising:
- (a) a pair of substantially rigid, substantially vertical front legs spaced apart from each other;
- (b) a pair of substantially parallel, nondeflecting outer armrests disposed in spaced relation to one another, each armrest extending rearwardly from a respective one of the front legs;
- (c) a substantially horizontal seat support means secured to and extending between the legs below the armrests;
- and
- (d) a pair of rearwardly extending, substantially horizontal, downwardly deflecting seat means having a front and a rear, each seat means defining an independent seat and each seat means being independently cantilevered below the armrests from the seat support means at the front of the seat means so that each seat means can provide a rocking motion that increases rearwardly while each seat means is non-downwardly deflecting at its front, and
- wherein the front of each seat means of the chair and the front of the outer armrests are in substantially the same vertical plane for ease of ingress into and egress out of the seats.
