A wheelchair has a damping system to reduce the forward pitch of the wheelchair upon sudden deceleration or upon descent of a sloped surface. The damping system includes a clamp that selectively grips a shaft.
Claims23
A wheelchair with a damping system to reduce the forward pitch of the wheelchair upon sudden deceleration or upon descent of a sloped surface.
A wheelchair having a frame and a rear suspension pivotally connected to the frame, and a damping system to reduce the forward pitch of the wheelchair upon sudden deceleration or upon descent of a sloped surface, the damping system including a clamp that selectively grips a shaft pivotally mounted on the frame, thereby modifying the damping force applied to reduce the forward pitch of the wheelchair, where the rear suspension is connected to the damping system in a manner that increases the damping force as the rear suspension system is pivoted from a neutral position upon the experiencing of forward pitch by the wheelchair.
A wheelchair having a frame and a rear suspension pivotally mounted to the frame, the wheelchair also having a damping system to reduce the forward pitch of the wheelchair upon sudden deceleration or upon descent of a sloped surface, where the rear suspension is connected to the damping system in a manner that progressively increases the damping force as the rear suspension is pivoted from a neutral position upon the experiencing of forward pitch by the wheelchair.
A wheelchair with a damping system to reduce the forward pitch of the wheelchair upon sudden deceleration or upon descent of a sloped surface, the damping system being configured to progressively resist forward pitch of the wheelchair in a manner such that increased forward pitch of the wheelchair causes an increased damping force resisting forward pitch.
