Abstract: An actuator comprises an actuator member and an assist mechanism. The assist mechanism comprises an assist element that is adapted to store energy to assist in moving the actuator member. The assist element is carried between two members. The members act upon the assist element to cause the assist element to store energy when the actuator member is moved in an extended direction and release the energy when the actuator member is moved in a retracted direction, whereby the retracted direction is opposite to the extended direction. The actuator is for use in moving the seat relative to the frame.

Abstract: A wheelchair swing-arm is adapted to be pivotally connected to a wheelchair base frame and support a wheelchair drive wheel. A fender is supported in a substantially fixed position relative to the wheelchair swing-arm. A method for attaching a fender to a wheelchair includes the steps of providing a wheelchair having a base frame and a swing-arm pivotally connected to the base frame and a drive wheel motor supported by the swing-arm, and supporting a fender in a substantially fixed position relative to the swing-arm.

Abstract: A wheelchair includes a base frame having a longitudinal axis, and a forward end and a rearward end joined by a first side frame and a second side frame, each side frame being generally parallel to the longitudinal axis. The wheelchair also includes a first motor and a second motor. A first mounting bracket is affixed on the first side frame and a second mounting bracket affixed on the second side frame. The first and second mounting brackets have a main body including a motor gear bore for securing the first motor or the second motor, a front tie down point directed toward the forward end of the frame, and a rear tie down point directed toward the rearward end of the frame.

Abstract: A support bracket for supporting a wheelchair seat frame relative to a wheelchair base frame includes a first end having a socket therein and a second end that is structured and configured to couple to a lateral rod which is connected to the seat frame. The socket is dimensioned and configured to receive an element which, in turn, is provided with a passage for receiving a lateral strut. The lateral strut is fixed relative to the wheelchair frame and is positionable in a substantially fixed position relative to the element in the socket in the first end of the support bracket.

Abstract: A wheelchair battery mounting system comprises a battery box including a battery box bottom and a battery box lid. The front end of the battery box lid is engageable with the front end of the battery box bottom. The rear end of the battery box bottom is fixed relative to the wheelchair frame. The rear end of the battery box lid is releasably engageable with wheelchair frame to fix the rear end of the battery box lid relative to the rear end of the battery box bottom. The rear end of the battery box bottom may be fixed relative to the rear end of a battery box support. The battery box support may comprise braces each having a front and rear end respectively attached to a front and rear cross tube of the wheelchair. The battery box bottom may have a stepped profile that complimentary in shape to a stepped profile of the battery box lid. A wheelchair may be comprised of a battery mounting system as set forth above.
