Abstract
A reclining chair having a back rest member which may be reclined. In one embodiment the reclining chair has means to allow it to be tilted. A pivotable joint is provided along the upper support members of the chair which allow such members to be pivotably bent proximate their midsection thereby allowing a greater degree of tilt of the seat member situate thereon than would otherwise be the case if there was no pivotable joint and the upper support members and the seat member thereon were tilted by simply lowering one end thereof. In another aspect, a lower leg support member is provided which rotatably extends upon the back rest of the chair being reclined, so as to support the calves of a user of the chair in a substantially horizontal position when the chair back is likewise reclined to a substantially horizontal position.
Claims25
A reclining, tiltable chair, comprising:
- a pair of substantially identical, parallel frame members, positioned in mutually spaced apart relation with each other, each of said frame members comprising an upper support member, a front member, a lower member, and a rear member;
- said front member fixedly coupled at a lower end thereof to said lower member;
- said upper support member pivotably coupled at one end thereof to an upper end of said front member;
- said rear member coupled at an upper end thereof to said upper support member and at opposite end thereof pivotably coupled to said lower member;
- a back rest member disposed intermediate said frame members, having a point of pivotable coupling to said upper support members of each of said frame members to allow said back rest member to be pivotably reclined from a substantially vertical position to an inclined position;
- a seat member located intermediate said upper support members, positioned forwardly of the back rest member;
- said upper support member having opposite end and a pivotable joint untermediate said opposite ends thereof to allow bending of said upper support member;
- and
- adjustable support means, adapted to cause said upper support member to resist a downward weight of a person sitting on said seat member.

A reclining, tiltable chair, comprising
- a pair of substantially parallel frame members, positioned in mutually-spaced apart from each other, each of said frame members comprising an upper support member, a front member, a lower member, and a variable length rear member;
- said front member fixedly coupled at a lower end thereof to said lower member;
- said upper support member pivotably coupled at a first end thereof to an upper end of said front member;
- said variable length rear member pivotably coupled at a lower end thereof to said lower member, and at an upper end thereof coupled to a second end of said upper support member;
- a back rest member disposed intermediate said frame members, pivotably coupled to said upper support members at a point of pivotable coupling to said upper support members situated approximately intermediate first and second ends thereof to allow said back rest member to be pivotably reclined from a substantially vertical position to an inclined position;
- a seat member situate intermediate said upper support members, positioned forwardly of the back rest member;
- the upper support member, intermediate the point of pivotable coupling to the back rest member and said second end thereof, having a pivotable joint to allow bending of the upper support member and thereby tilting of said seat member situated therebetween;
- and
- an extendable cylinder member pivotably coupled at one end thereof to the corresponding upper support member, adapted to exert an upward and rearward force on said upper support member, and pivotably coupled at its other end to said lower member, adapted to cause said upper support member to resist a downward weight of a person sitting on said seat member.

A reclining, tiltable, portable chair suitable for geriatric patients and invalids, comprising:
- a pair of substantially parallel frame members, positioned in mutually spaced apart relation with each other, each of said frame members comprising a substantially horizontal upper support member, a substantially vertical front member, a lower substantially horizontal lower member, and a rear member;
- said front member fixedly coupled at a lower end thereof to said lower horizontal member;
- said upper support member pivotably coupled at one end thereof to said front member proximate an upper end thereof;
- said rear member fixedly coupled at one end thereof to said upper support member and at opposite end thereof pivotably coupled to said lower horizontal member;
- a back rest member disposed intermediate said frame members, having a point of pivotable coupling to said upper support members of each of said frame members to allow said back rest member to be pivotably reclined from a substantially vertical position to an inclined position;
- a seat member located intermediate said upper support members, positioned forwardly of the back rest member;
- said upper support member, at a position thereon intermediate said point of pivotable coupling to said back rest member and said rear member, having a pivotable joint to allow bending of said upper support member;
- adjustable support means, adapted to cause said upper support member to resist a downward weight of a person sitting on said seat member, comprising an extendable member, pivotably coupled at one end to said upper support member rearward of said pivotable joint;
- and
- first and second pairs of wheel means, said first pair located respectively proximate the point of fixed coupling of each of said first member to said lower horizontal member, and extending downwardly from said lower horizontal member, and said second pair located respectively at an opposite end of said support member and extending downwardly therefrom.
