Abstract
A collapsible stadium seat with a seat member that defines a base plane, and seat membrane support members. A seat membrane is coupled to and spans the space between the seat membrane support members to define a user seating surface. The seat membrane is angled backward such that its front portion is farther from the base plane than is its back portion. There is also a cantilevered back that is pivotably coupled to the seat member and includes first and second spaced back support members. A back membrane is coupled to the support members. The support members are angled or curved to define a lumbar support region. There are back adjustment mechanisms that can be locked and unlocked and allow the back to pivot, to establish a comfortable use position.
Claims20
A collapsible stadium seat, comprising;
- i) a seat member, comprising:
- a frame base that defines a base plane;
- first and second spaced seat membrane support members supported by the frame base;
- and
- a seat membrane with a front end and a back end, wherein the seat membrane is coupled to and spans the space between the first and second seat membrane support members to define a user seating surface;
- ii) a cantilevered back that is pivotably coupled to the seat member, comprising:
- first and second spaced back support members each including a first portion and a second portion, wherein the first and second portions of each back support member lie at an obtuse angle to each other, and wherein the second portion of each back support member is farther from the base plane than is the first portion of the respective back support member;
- a back membrane that is coupled to and spans the space between the first and second back support members to define a user back-supporting surface, wherein the back membrane is coupled to both the first and second portions of each of the first and second back support members such that the back membrane is held in tension, creating a curved lumbar support region for a user;
- and
- a brace bar connected between the first and second back support members and spaced from the back membrane;
- and
- iii) a back support and adjustment mechanism, comprising:
- first and second pivoting mechanisms, one located at an intersection of the first back support member and the seat member and the other located at an intersection of the second back support member and the seat member, wherein the first and second pivoting mechanisms are configured to establish at least a deployed configuration wherein a distal end of the back extends away from the seat member base plane and a collapsed configuration wherein the distal end of the back lies closer to the seat member base plane.

- and
- a seat membrane with a front end and a back end, wherein the seat membrane is coupled to and spans the space between the first and second seat membrane support members to define a user seating surface, wherein the seat membrane is angled backward such that its front portion is farther above the base plane than is its back portion;
- ii) a cantilevered back that is pivotably coupled to the seat member, comprising:
- first and second spaced back support members each including a first portion and a second portion, wherein the first and second portions of each back support member lie at an obtuse angle to each other, and wherein the second portion of each back support member is farther from the base plane than is the first portion of the respective back support member;

A collapsible stadium seat, comprising;
- i) a seat member, comprising:
- a frame base that defines a base plane;
- and
- a cushion with an upper surface, a front end and a back end, wherein the cushion is configured to be removably coupled to the frame base such that the cushion upper surface is angled from the base plane at an acute angle, with the cushion front end farther from the base than the cushion back end;
- ii) a cantilevered back that is pivotably coupled to the seat member, comprising:
- first and second spaced back support members each including a first angled portion and a second angled portion, wherein the first and second angled portions of each back support member lie at different angles to the base plane and the second angled portion of each back support member is farther from the base than is the first angled portion of the respective back support member, wherein the upper angled portion and the lower angled portion of the back support members extend toward a front of the seat member;
- and
- a back membrane that is coupled to and spans the space between the first and second back support members to define a user back-supporting surface, wherein the back membrane is coupled to the upper angled portions and the lower angled portions of the first and second back support members such that the back membrane is held in tension and is taut, creating a lumbar support region for a user;
- and
- iii) a back support and adjustment mechanism, comprising:
- first and second pivoting mechanisms, one located at an intersection of the first back support member and the seat member and the other located at an intersection of the second back support member and the seat member, wherein the first and second pivoting mechanisms are configured to establish at least a deployed configuration wherein a distal end of the back extends away from the seat member base plane and a collapsed configuration wherein the distal end of the back lies closer to the seat member base plane.
