Abstract
A personal mobility vehicle for use by disabled persons to perform certain tasks such as playing golf is described. The mobility vehicle which in one embodiment comprises a golf cart includes a seat assembly that can be (i) swiveled to permit the rider to face sideways of rearwardly and (ii) tilted to move the rider into a pseudo-standing stance. Accordingly, the rider can address and hit a golf ball in a similar manner as a person who is not disable while being supported by the vehicle's seat. In the preferred embodiment, a canopy is provided that automatically retracts as the seat is tilted.
Claims46
A mobility vehicle for movement over a ground surface, the mobility vehicle comprising:
- a vehicle framework for a golf cart, the framework including front, rear, left and right sides;
- a wheeled drive mechanism, the drive mechanism coupled to the vehicle framework;
- and
- a seat assembly, the seat assembly coupled with the framework for swiveling movement about a swivel axis of rotation to move the seat between a first rotational position facing the front side to at least a second rotational position facing outwardly from one of the left, right and rear sides, the seat assembly including (i) a seat bottom, the seat bottom having a seat bottom support frame and a seating surface disposed on the seat bottom support frame, the seating surface bounded by a front end, a rear end that is longitudinally spaced from the front end, and spaced left and right sides that extend from the front end to the rear end, and, (ii) a seat back, the seat back having a seat back surface;
- and (iii) a tilting mechanism coupled with the seat bottom and the seat back, the tilting mechanism being configured for moving the seat assembly between a first and second position, the seat bottom being generally horizontal and the seat back being generally vertical in the first position forming a first angle between the seating surface and the seat back surface, and the seat bottom being tilted at least 25 degrees relative to horizontal in the second position forming a second angle between the seating surface and the seat back surface, the second angle being greater than the first angle;
- wherein a user in the seat can (a) swivel the seat from the first rotational position facing towards the front of the vehicle to the second rotational position facing outwardly from at least one of the left, right and rear sides and (2) raise the seat assembly into the second position placing the user into a pseudo-standing position with the user's feet substantially in contact with a ground surface to enable the user to hit a golf ball located on the ground surface with a golf club.

A seat assembly for use on a personal mobility vehicle, the seat assembly comprising:
- a seat bottom, the seat bottom having a front edge, a rear edge and a seat surface;
- a seat back, the seat back having a bottom, a top edge and a seat back surface;
- a swivel mechanism, the swivel mechanism comprising a mounting portion adapted for coupling with the personal mobility vehicle, and a swiveling portion permitting swivel movement of the seat back and seat bottom in a generally horizontal plane relative to the mounting portion;
- and
- a tilting mechanism coupled to the seat back, the seat bottom and the swivel portion of the swivel mechanism, the tilting mechanism being configured for moving the seat bottom between a first and second positions, the seat bottom being generally horizontal and the seat back being generally vertical in the first position forming a first angle between the seating surface and the seat back surface, and the seat bottom being tilted at relative to horizontal in the second position forming a second angle between the seating surface and the seat back surface, the second angle being greater than the first angle;
- wherein the tilt mechanism further includes a linear actuator, the linear actuator being pivotally connected to the seat back.

A mobility vehicle for movement over a ground surface, the mobility vehicle comprising:
- a chassis;
- a wheeled drive mechanism, the drive mechanism coupled to the chassis;
- and
- a seat assembly coupled with the chassis, the seat assembly including (i) a seat back, (ii) a seat bottom, (iii) a seat base framework, and (iv) an articulated four bar linkage connecting the seat base framework, the seat back and the seat bottom and configured for moving the seat bottom from a fully retracted position, wherein the seat bottom is substantially horizontal, to a fully tilted position, wherein the seat bottom forms an angle with a horizontal plane, while maintaining the seat back at a relatively constant angle relative to the horizontal plane, and (iv) a linear actuator, the linear actuator pivotally connected to the seat back at one end for moving the seat between a fully retracted position and a fully tilted position.
1 more element
A mobility vehicle for movement over a ground surface, the mobility vehicle comprising:
- a chassis;
- a wheeled drive mechanism, the wheeled drive mechanism being coupled to the chassis;
- a seat assembly coupled to the chassis, the seat assembly including a seat bottom that is moveable between a fully retracted position, wherein the seat bottom is horizontal, to a fully tilted position, wherein the seat bottom forms an angle with a horizontal plane;
- and
- a retractable canopy assembly including a canopy, the canopy assembly being pivotally coupled with the seat assembly, wherein the seat assembly is substantially covered by the canopy in the fully retracted position, and the seat assembly is substantially not covered by the canopy in the fully tilted position.

A personal mobility vehicle comprising:
- a chassis;
- a wheeled drive mechanism;
- and
- a seat assembly including (i) a swivel frame, the swivel frame being coupled to the chassis for swivel movement around a substantially vertical swivel axis, (ii) a seat bottom having front and rear edges, the seat bottom being pivotally attached to the swivel frame along a substantially horizontal pivot axis proximate the front edge, the seat bottom being tiltable about the horizontal pivot axis by raising the rear edge of the seat bottom from a horizontal orientation to a second orientation forming an angle with a horizontal plane, (iii) a seat back that is pivotally connected with the rear edge of the seat bottom, wherein the seat back is raised with the rear edge of the seat bottom, while maintaining a generally vertical orientation;
- and (iv) a linear actuator, the linear actuator being pivotally attached to the seat back and coupled with the swivel frame, wherein actuation of the linear actuator raises the seat back and the pivotally connected seat bottom rear edge upwardly.
