A counterbalance includes a first attachment strap, and an arbor rotatably supported by the first attachment strap. A second attachment strap is attached to the arbor, and is rotatable with the arbor about a winding axis. A spiral spring interconnects the first attachment strap and the second attachment strap. A spring support is attached to the second attachment strap. The spring support includes an annular wall that is disposed circumferentially about and concentric with the winding axis. The annular wall is radially positioned relative to the winding axis to contact an outermost coil of spiral spring, to position the spiral spring in a spiral orientation about the winding axis, such that each coil of the spiral spring moves away from the winding axis with a substantially constant angular velocity to provide a substantially equal radial spacing between adjacent coils of the spiral spring.

A door handle assembly for use with a vehicle door comprising a door paddle including an actuation arm, supported to pivot about a first axis such that lateral acceleration of the paddle and actuation arm relative to the door produces a first moment about the first axis, and masses engaged with the actuation arm and supported to pivot about a second axis, the masses being arranged such that lateral acceleration of the masses relative to the door produces a second moment about the first axis that is substantially equal in magnitude and opposite in direction to the first moment.

A closure assembly with a shape memory polymer seal is provided for use with a vehicle. The closure assembly includes a frame member configured for attachment to the vehicle body to selectively transition from a closed position to an open position. The seal structure includes a base portion elongated along and attached to a peripheral edge of the frame member or the vehicle body, and a flexible contact portion extending integrally from the base portion and configured for sealing communication with an opposing surface. A thermally-activated smart material (TASM), namely a shape memory polymer member, is disposed inside a cavity within the contact portion. A thermoelectric device is in thermal communication with the TASM, and is characterized by a thermal differential when current flows therethrough. The TASM is activated in response to the thermal differential of the thermoelectric device, thereby altering at least one physical property of the TASM.

A blocker member is mounted on the vehicle body adjacent the floor mounted door track and includes a housing and a blocker lever which is pivotally mounted on the housing. The blocker lever is operably connected to the fuel filler door by a cable. When the fuel filler door is opened, the cable is tensioned and pivots the blocker lever to an extended position in which the blocker lever extends into the path of sliding movement the door. Thus, whenever the fuel filler door is open, the sliding door is blocked from sliding open into engagement with the fuel filler door. The blocker member preferably includes a resilient bumper against which the blocker lever seats in order to absorb energy when the door is slid into engagement with the blocker lever. The cable is preferably connected to the blocker by an actuator lever and spring arrangement by which the cable and actuator lever have a range of movement beyond the movement of the blocker lever so as to accommodate any misadjustment of the cable connecting the fuel filler and the blocker member.
