  • Patent number: 5992555
    Abstract: An apparatus for supporting a power train in a vehicle body having a monocoque structure that includes a bumper reinforcer, which is arranged in front of a passenger compartment, side members, and a toe board. The supporting apparatus is provided with first and second push rods, and a torque rod for supporting the power train. The first and second push rods are connected to the bumper reinforcer and support the front side of the power train. During a head-on collision, the first and second push rods cause the power train to be displaced toward the passenger compartment in a downwardly inclined direction. In the same manner, the torque rod is connected to the toe board and supports the rear side of the power train. During the head-on collision, the torque rod also causes the power train to be displaced toward the passenger compartment in a downwardly inclined direction.

  • Patent number: 5125702
    Abstract: A housing for a door lock device has an irregular outer perimeter with inside and outside curved corners. A sub housing for the door lock device has a similarly configured outer perimeter coupled to the perimeter of the housing. An O-ring is inserted in a groove in the housing perimeter for sealing the perimeters of the housing and sub-housing. The O-ring has a plurality of spaced gripping portions that have a width greater than the width of the groove before insertion therein for keeping the O-ring from springing out of the groove during assembly.

  • Patent number: 5106133
    Abstract: A power actuator for a door lock device comprising an electric motor driving a worm gear, a gear wheel driven by the worm gear, a handling lever driven by an arcuate projection on the gear wheel and a locking arm rotated by the handling lever. The wheel gear has a peripheral groove with a portion of reduced width for supporting opposite ends of an elongate coil spring; which is compressed in a direction corresponding to the rotation of the gear wheel. An arcuate segment projects axially from the gear wheel. The opposite ends of the arcuate segment and the handling lever is shaped to provide point contact with the handling lever upon initial engagement and surface contact as the arcuate projection moves the handling lever to the locking and unlocking position. A contact is disposed on a base plate; and contacts on the handling lever slidably engage the contacts on the base plate to detect the locking and unlocking position of the handling lever.

  • Patent number: 5035454
    Abstract: A door lock device having a key handling lever for rotating a locking arm selectively to a locked and unlocked position. A switch for detecting the locked and unlocked position of the locking arm has a main body member attached to a sub housing of the device. An arm element is pivotably attached to the main body member and is connected to and movable with the locking arm. A first switch contact is formed on a surface of the main body member; and a second switch contact is formed on the arm element. The switch contacts are in engagement when in a locked condition and out of engagement when in an unlocked condition.
