Abstract: In an aspect, a door control system is provided for a vehicle door and includes a pushrod and a locking device. The pushrod has a first end connected to one of the vehicle body and the vehicle door. At least a portion of the locking device is mounted to the other of the vehicle body and the vehicle door. The locking device includes a leadscrew, a leadscrew nut mounted on the leadscrew, a housing including a guide path, and a brake. The pushrod has a second end connected to the leadscrew nut. The leadscrew nut is constrained against rotation but is slideable along the guide path by movement of the pushrod, which causes rotation of the leadscrew. The brake is positionable in a braking position in which the brake prevents rotation of the leadscrew, and a release position in which the brake permits rotation of the leadscrew.

Abstract: In an aspect, a check arm for a vehicle door is provided, and includes a body, a pivot connector and an end stop. The body has a length and defines a longitudinal axis, and has a first body end and a second body end. The pivot connector is positioned at the first body end and is configured for pivotally connecting the check arm to one of a vehicle body and a vehicle door. The end stop is positioned at the second body end, and is positioned to limit the amount of withdrawal of the check arm from a check arm keeper on the other of the vehicle body and the vehicle door. The body includes a plurality of elongate structural fibers and a binder that connects the structural fibers together. Each structural fiber extends longitudinally along substantially the length of the body.

Abstract: The present assembly relates to a link assembly for a chair. The assembly includes a frame link for connecting to a frame of the chair and a back support link for connecting to a back support of the chair. The frame link and the back support link are pivotably connected in order to facilitate displacement of the back support according to movement of a back frame of the chair. An adjustable pivot point is located on one of the links for selectively adjusting the extent of displacement of the back support relative to the back frame.

Abstract: A wheelchair incorporates a tilt mechanism with a center of gravity compensation by employing a rotary actuator. The actuator is secured to the underside of the seat and has an arm pivotally secured to the frame. A seat pivot axis is located on a movable member that allows the axis to shift from a rear portion of the wheelchair toward a front portion as the seat is tilted from its upright position to a tilted position. This assures that the center of gravity of the user is maintained within the wheelbase of the chair, i.e., compensates for center of gravity.

Abstract: A reduced shear reclining seat back assembly employs a single rotary actuator for reclining a seat back relative to a seat portion and controlling movement of a seat back member in response to the reclining operation. A rotary actuator includes a first arm pivotally secured to the seat back, preferably through a link which is connected to the movable back member. A second arm of the actuator is pivotally secured to the seat portion. As the angle between the first and second arms decreases, the seat back reclines and the movable seat back member is drawn toward a seat pivot axis. Likewise, when the angle between the arms increases, the seat back is brought to an upright position and the movable seat member travels away from the seat pivot axis.
