A head rest apparatus comprises a sole stay, a head rest main body movably supported on the sole stay, a guide rod fixed in the head rest main body, a rail disposed in the head rest main body and fixed on the sole stay, a guide member slidably supported on the guide rod and the rail, a screw rotatably supported in the head rest main body, a nut supported on the rail and engaged with the screw, a cushion disposed between the rail and the nut, and a motor connected to the screw or the nut. A load imparted to the head rest main body is absorbed by the sliding movement of the guide member and the distortion of the cushion.

A headrest assembly for vehicle seats includes a first stationary link and a second link connected to the first link and side walls of a bracket for padded member. A rod is rotatably connected to the first link and received in slots on the bracket. When a motor mounted on the bracket is actuated, a screw member engaged with a nut member which is fixed on the rod causes the bracket to be swiveled.

A lumbar support includes a seat back body, a lumbar plate, and plate moving means for moving the lumbar plate back and forth. The plate moving means includes a base portion supported by the seat back body and having a pair of oblong holes, a screw rod supported for free rotation on the base portion and having a male screw on its outer surface, a nut member having a centrally formed female screw threadedly engaged with the male screw, the nut member being moved axially of the screw rod by turning the latter, an anchor member connecting the lumbar plate to the nut member and having a ring-shaped pivot portion at an end thereof on the side of the nut member, and a distance compensating pin passed through the ring-shaped pivot portion and supported at the oblong holes so as to be movable in the longitudinal direction of the oblong holes. When the nut member is moved axially of the screw rod, the distance compensating pin moves longitudinally of the oblong holes so as to compensate for a change in distance between the center of the ring-shaped pivot portions and the center of rotation of the screw rod.

A control apparatus of an opening and closing body for a vehicle includes a fully closed state detection means detecting a fully closed state of an opening and closing body for the vehicle, an authenticating means authenticating a user of the vehicle, a detection means detecting a command for an opening operation when the authenticating means and the portable unit authenticate each other, a driving means conducting the opening operation when the fully closed state and the command for the open operation are detected, wherein the detection means is a vibration sensor mounted at one of the opening and a butted surface of the opening and closing body for the vehicle, and the vibration sensor detects that an object is pinched between the opening and the opening and closing body for the vehicle at a closing operation.
摘要:
A device (20) for assembling a plastic-lens-forming casting mold includes a gasket clamping mechanism (22) which clamps a gasket (2) from its axial direction, a first mold push-in mechanism (23) which pushes in an upper mold (3) fitted in an upper open end of the gasket (2), and a second mold push-in mechanism (24) which pushes in a lower mold (4) fitted in a lower open end of the gasket (2). The gasket clamping mechanism (22) clamps the gasket (2) from the axial direction by a gasket-pressing ring (34) and lower mold ring (35). The first mold push-in mechanism (23) pushes the upper mold (3) into the gasket (2) by a gasket push-in member (58). The second mold push-in mechanism (24) includes a plurality of push pins (68) and pushes up the lower mold (4) to push it into the gasket (2).
