Abstract
A rollator with a tubular frame assembly includes a pair of U-shaped side frames connected by a front brace. Each side frame has a cross bar that extends between front legs and back legs of the frame. The side frames are pivotably attached to the front brace so that the side frames can fold inwardly. The rollator has a molded rigid seat that is mounted on pivot brackets to allow it to pivot upwardly out of the way of the user. The pivot brackets have an offset axis of rotation so that the seat is arranged in a curved area of the front brace when pivoted upwardly.

1-14. (canceled)
An ambulatory device, comprising:
- (a) two side frames, each side frame having a front leg and a back leg and a cross bar between the front leg and the back leg;
- (b) a seat pivotably mounted to the side frames;
- and
- (c) at least two support brackets operatively coupled to the seat, one of which is disposed on either side of the seat;
- and
- wherein each support bracket comprises one or more notches to engage at least one of the side frames so that the seat is supported on the side frames when the seat is placed in a lowered position.

An ambulatory device, comprising:
- (a) two side frames, each side frame having a front leg and a back leg and a cross bar between the front leg and the back leg;
- (b) a seat pivotably mounted to the side frames;

1 more element
An ambulatory device comprising:
- (a) two side frames, each side frame having a front leg and back leg;
- (b) a brace connecting the front leg of each of the frames;
- (c) a seat having first and second sections, the second section pivotably coupled to the frames, the seat capable of being disposed in:
- a first position in a substantially horizontal orientation;
- and
- a second position in a substantially vertical orientation;
- and
- (d) at least two support brackets integral with the seat, one support bracket being disposed downwardly on either side of the seat with respect to the first position to secure the seat to the frames when the seat is in the first position;
- wherein the support brackets provide support for the ambulatory device when the seat is in the first position such that when lateral force is applied to the side frames, the lateral force is distributed along the support brackets and across the seat.

An ambulatory device, comprising:
- (a) a first side frame and a second side frame, each side frame having a front leg and a back leg;
- and
- (b) a seat pivotally connected to the first side frame front leg and the second side frame front leg, the seat capable of being disposed in a first position oriented substantially horizontally and a second position oriented substantially vertically, and the seat including an undersurface having at least first and second pluralities of intersecting walls that, while the seat is in the first position, extend downward from the seat undersurface defining a plurality of downward openings.
An ambulatory device, comprising:
- (a) a first side frame and a second side frame, each side frame having a front leg, a back leg, and a cross bar between the front leg and the back leg;
- (b) a seat pivotally connected to the first side frame front leg and the second side frame front leg, the seat capable of being disposed in a first position oriented substantially horizontally and a second position oriented substantially vertically;
- (c) at least two downwardly curving support brackets, each downwardly curving support bracket extending outwardly from the seat to engage a respective one of the cross bars of one of the side frames;
- and
- (d) at least a first continuous wall extending from one support bracket, under the seat, and to another support bracket, and that, while the seat is in the first position, extends downward from a seat undersurface.
