Abstract

A walker seat may include a seat bottom and a support structure. The seat bottom may include an anterior region, a posterior region, an upper side, and a lower side. The lower side may include a central segment retention portion. The support structure may include a central segment, a left-side segment, and a right-side segment. The central segment may be retained by the central segment retention portion. The left-side segment may be extendable from a left side of the central segment, whereby the left-side segment extends beyond a left side of the seat bottom. Similarly, the right-side segment may be extendable from a right side of the central segment, whereby the right-side segment extends beyond a right side of the seat bottom.

Claims (75)

1. An apparatus comprising:

a seat bottom;

a support structure arranged underneath the seat bottom, wherein the support structure includes:

a central segment;

a left-side segment extendible beyond a left side of the seat bottom and removably engageable with the central segment; and

a right-side segment extendible beyond a right side of the seat bottom and removably engageable with the central segment; and

a spring extending through the central segment, attached to the left-side segment, and attached to the right-side segment.

2. The apparatus of claim 1 , wherein the seat bottom further comprises an attachment portion in a posterior region of the seat bottom and configured to attach to an additional member, such that the seat bottom can rotate about the additional member.

3. The apparatus of claim 2 , further comprising a mounting member configured to mount to another structure, and wherein the additional member comprises the mounting member.

4. An apparatus comprising:

a seat bottom;

a central segment retention portion arranged:

on a lower side of the seat bottom; and

away from a posterior edge of the seat bottom by a distance;

a support structure including:

a central segment retained by the central segment retention portion;

a left-side segment extendable from a left side of the central segment, whereby the left-side segment extends beyond a left side of the seat bottom, wherein the left-side segment is removably engageable with the left side of the central segment;

a right-side segment extendable from a right side of the central segment, whereby the right-side segment extends beyond a right side of the seat bottom, wherein the right-side segment is removably engageable with the right side of the central segment; and

a spring extending through the central segment, attached to the left-side segment, and attached to the right-side segment.

5. The apparatus of claim 4 , wherein the central segment retention portion is located in an anterior region of the seat bottom.

6. The apparatus of claim 5 , further comprising:

a left-side segment retention portion configured to releasably retain the left-side segment; and

a right-side segment retention portion configured to releasably retain the right-side segment,

wherein the right-side segment retention portion and the left-side segment retention portion are located on at least one of the lower side of the seat bottom or the central segment.

7. The apparatus of claim 4 , wherein:

the left-side segment is removably engageable with the left side of the central segment; and

the right-side segment is removably engageable with the right side of the central segment.

8. An apparatus comprising:

a seat bottom;

a central segment retention portion arranged on a lower side of the seat bottom; and

a support structure including:

a central segment retained by the central segment retention portion;

a left-side segment telescopically arranged with the central segment and telescopically extendable from a left side of the central segment, whereby the left-side segment extends beyond a left side of the seat bottom; and

a right-side segment telescopically arranged with the central segment and telescopically extendable from a right side of the central segment, whereby the right-side segment extends beyond a right side of the seat bottom.

9. The apparatus of claim 8 , wherein the seat bottom further comprises an attachment portion in a posterior region of the seat bottom and configured to attach to an additional member, such that the seat bottom can rotate about the additional member.

10. The apparatus of claim 9 , further comprising a mounting member configured to mount to another structure, and wherein the additional member comprises the mounting member.

11. The apparatus of claim 10 , wherein the mounting member comprises:

an elongated portion having a left side and a right side;

a left-side mounting structure on the left side of the elongated portion, wherein the left-side mounting structure is mountable to the another structure; and

a right-side mounting structure on the right side of the elongated portion, wherein the right-side mounting structure is mountable to the another structure.

12. The apparatus of claim 8 , wherein the central segment retention portion is located in an anterior region of the seat bottom.

13. An apparatus comprising:

a mounting member including:

an elongated portion having a left side and a right side;

a left-side mounting structure on the left side of the elongated portion, wherein the left-side mounting structure is mountable to a walker; and

a right-side mounting structure on the right side of the elongated portion, wherein the right-side mounting structure is mountable to the walker;

a seat bottom including:

an anterior region;

a posterior region;

an upper side; and

a lower side;

a central segment retention portion underneath the anterior region of the lower side;

an attachment portion rotatably attached to the elongated portion of the mounting member; and

a support structure including:

a central segment retained by the central segment retention portion;

a left-side segment extendable from a left side of the central segment, whereby the left-side segment extends beyond a left side of the seat bottom, wherein the left-side segment is removably engageable with the left side of the central segment;

a right-side segment extendable from a right side of the central segment, whereby the right-side segment extends beyond a right side of the seat bottom, wherein the right-side segment is removably engageable with the right side of the central segment; and

a spring extending through the central segment, attached to the left-side segment, and attached to the right-side segment.

14. The apparatus of claim 13 , wherein the elongated portion comprises a U-shape.

15. An apparatus comprising:

a mounting member including:

an elongated portion having a left side and a right side;

a left-side mounting structure on the left side of the elongated portion, wherein the left-side mounting structure is mountable to a walker; and

a right-side mounting structure on the right side of the elongated portion, wherein the right-side mounting structure is mountable to the walker;

a seat bottom including:

an anterior region;

a posterior region;

an upper side;

a lower side including a central segment retention portion in the anterior region; and

an attachment portion rotatably attached to the elongated portion of the mounting member; and

a support structure including:

a central segment retained by the central segment retention portion;

a left-side segment extendable from a left side of the central segment, whereby the left-side segment extends beyond a left side of the seat bottom, wherein the left-side segment is removably engageable with the left side of the central segment; and

a right-side segment extendable from a right side of the central segment, whereby the right-side segment extends beyond a right side of the seat bottom, wherein the right-side segment is removably engageable with the right side of the central segment,

wherein the left-side segment, right-side segment, and central segment comprise a telescoping arrangement.
