Abstract: The presence of a child restraint seat on a vehicle seat is detected by movement of a pair of anchors from a first position to a second position when the child restraint seat is coupled with straps to the anchors. The anchors are pivotally or deflectively mounted on a cross bar which extends between side frame members within the back of the vehicle seat. Upon a sensor detecting the presence of the child restraint seat, an associated air bag is disabled so that the air bag will not be deployed against a child sitting in the child restraint seat if the car is in an accident. Upon removing the child restraint seat, the anchors return to the first position in which the sensor again enables the air bag for deployment because, in the absence of a child restraint seat, an occupant of the seat is more likely to be an adult than a child.

Abstract: A first housing rotatably supports a steering shaft having an end portion coupled to a steering wheel. A second housing engages with the first housing via two impact energy absorbing rings separate from each other in the axial direction. The first housing and the second housing are relatively movable in the axial direction. One of the first housing and the second housing has first and second impact energy absorbing protrusions projected from positions between the impact energy absorbing rings separately in the axial direction so as to contact with the circumferential surface of the other of the first housing and the second housing. The impact energy absorbing protrusions therefore reduce the load applied to the impact energy absorbing rings in usual steering. Further, the impact energy absorbing rings reduce the load due to frictional resistance in impact energy absorption.

Abstract: A seat belt device includes a lap anchor and connector assembly that are engaged by a latch pressed by a first latch spring. In the event that inertia force is applied to the connector assembly in a direction that tends to urge the disengagement of the connector assembly and the lap anchor, the latch tries to move in the direction of disengagement. The attempted movement causes retaining shoulder portions of the latch to abut against latch holding portions of a second latch spring, thereby preventing movement of the latch in the direction of disengagement. Thus, engagement of the connector assembly and the lap anchor is stable, and disengagement of the connector assembly and the lap anchor is prevented.

Abstract: A first flange and a second flange are superposed and fastened with a bolt and a nut in a fastening operation, to implement a fastening structure used at temperature lower than atmospheric temperature for the fastening operation. Assuming that the first flange has a thickness L1 and a coefficient of linear expansion ?1, the second flange has a thickness L2 and a coefficient of linear expansion ?2, superposed first flange and second flange have a thickness L, and the bolt has a coefficient of linear expansion ?, a relation of L·??L1·?1+L2·?2 is satisfied, i.e. heat shrinkage of the bolt is not smaller than the total heat shrinkage of the first and second flanges. Thus, impairment of sealing property due to heat shrinkage is avoided at a flange junction used at low temperature.

Abstract: A vending machine cabinet is retained in a closed position by a hook that is engaged by a vertically moveable latch bar that can be latched closed without requiring a solenoid. The latch bar is moved by means of a cam attached to one of the hooks. Prior to engaging the hook, an angled surface of the cam engages a surface defined by the opening in the latch bar. As the door is closed, the cam rotates through an angle thereby lifting the latch bar until the upwardly extending finger of the hook can move through the opening of the latch bar. When the door is fully closed, the surface of the cam is moved from beneath the edge of the opening in the latch bar thereby allowing the latch bar to drop behind the hook, latching the door closed.

Abstract: A wind-powered brake system which is operated to brake a movable body when a driving force of a driving source for moving the movable body should be decreased, is described. The object of the present invention is to assist normal braking, to reduce a heat energy loss, and to perform braking suitable for a necessary braking force. A wind tunnel 34 is installed in each armrest 16 of a wheelchair 10. In braking, a load for generating power is put on rotary vanes 40 provided in the wind tunnel 34. Thus, the flow of wind is obstructed, and this functions as a braking force. It is thus possible to brake the wheelchair 10 using a combination of a brake mechanism of an electric motor and a wind-powered brake system. The burden on the brake mechanism of the electric motor can be lessened, and early wear and performance degradation due to frictional heat can be suppressed. By assisting the brake function of the electric motor, the amount of heat energy released from the electric motor into the air can be reduced.

Abstract: A condition of hydraulic fluid conducted from an accumulator to an operation device via a pressure control unit, is evaluated by determining a pressure (Pa) of the fluid in a flow path interconnecting the accumulator and the control unit, and determining a stabilization time (T) when an absolute value of a pressure gradient per unit time of the pressure falls below a predetermined value. A pressure drop (?Pa) of the pressure is determined during a period between a time (T0) when the pressure begins to decrease, or at a time before the time (T0) and the stabilization time (T). The pressure drop is compared with a predetermined pressure drop that is obtainable under normal conditions. An increase in (?Pa) can signify the entry of air into the hydraulic fluid, or a leakage of the hydraulic fluid.
