Abstract
A seat assist device is described. The seat assist device includes a base, a lift platform having a front portion and a rear portion, with the front portion of the lift platform being pivotally connected with the base. A lifting arm is connected with the rear portion of the lift platform. The lifting arm extends from the lift platform to project beyond the front portion of the lift platform, with the lifting arm terminating in handles for grasping by a user. A lift bar is pivotally connected between the base and the lifting arm, whereby a user sitting upon the seat assist device can press downward on the handles to cause the rear portion of the lift platform to rise and, in doing so, assist the user in rising from a seated position.
Claims11
A seat assist device, comprising:
- a base, the base including frame members to form a chair, including a backrest and one or more legs;
- a lift platform having a front portion and a rear portion, with the front portion of the lift platform being pivotally connected with the base;
- a lifting arm connected with the lift platform, the lifting arm extending from the lift platform to project beyond the front portion of the lift platform;
- a foot pedal pivotally connected with the base and operably connected with the lift platform such that depression of the foot pedal causes the lift platform to lift, whereby a user can press downward on the foot pedal to cause the rear portion of the lift platform to rise and, in doing so, assist a person in rising from a seated position;
- a first linkage connected with the foot pedal that pivots about a pivot point;
- a lift linkage operably connected between the first linkage and the lift platform, whereby when the foot peddle is depressed, the first linkage pivots about the pivot point to lift the lift linkage, which in turn forces the lift platform to lift;
- a lift bar pivotally connected between the base and the lifting arm;
- and
- a slide slideably connected with the lifting arm, and wherein the lift bar is pivotally connected with the slide, thereby pivotally connecting the lift bar with the lifting arm.
