Abstract

Seats that are moveable from a seating orientation, which allows a user to sit on the seat, to a standing orientation, where the seat at least partially supports the user in a standing posture are disclosed. At least a portion of the seat is moveable away from the user's legs when the seat is in the standing orientation.

First claim

The invention claimed is:

1. A method of assisting movement from a seated position to a standing position comprising:
pivoting both a first portion and a second portion of a seat from a substantially horizontal seating orientation to a substantially vertical standing orientation to move a user from a seated position to a standing position; and
moving the second portion of the seat relative to the first portion such that the second portion moves away from the user's legs.

2. The method of claim 1 wherein the second portion is a forward support portion and the first portion is a rearward portion, and the forward support portion automatically moves with respect to the rearward portion away from the user's legs as the seat is moved from the seating orientation to the standing orientation.

3. The method of claim 1 further comprising pivoting both the first portion and the second portion of the seat relative to a seat back as the seat is moved from the seated position to the standing position.

4. The method of claim 1 wherein when the seat is in the seating orientation, the first portion has a first alignment with the second portion, and when the seat is pivoted to an intermediate position that is approximately midway between the seating orientation and the standing orientation, the first portion remains in the first alignment with the second portion.

5. The method of claim 4 wherein when the seat is pivoted from the intermediate position to the standing orientation, the second portion is pivoted relative to the first portion to a second alignment with the first portion that is different than the first alignment.

6. The method of claim 1 wherein both the first portion and the second portion pivot about a first pivot axis when moving from the seating orientation to the standing orientation and the second portion pivots about a second pivot axis different than the first pivot axis when moving relative to the first portion such that the second portion moves away from the user's legs.
