  • Patent number: 8307935
    Abstract: In a vehicle pop-up hood apparatus in which a rod is extended and a hood is pushed up by the operation of an actuator at a time of collision with a collision body, collision energy is absorbed with high efficiency when a collision load of a predetermined value or greater is input to an area near a hood pushed up position. Actuator (18) operates such that rod (20) moves in an axial direction toward a hood upper side, pushes up a rear edge side of hood rocker (12) and holds it at that position and, in that state, when a collision load of a predetermined value or greater acts from a hood upper side to near the pushed up position of the hood, push portion (54) slides along pushed up surface (38) of hinge arm (30) towards a vehicle rear side, and rod (20) is made to bend in conjunction therewith.

  • Patent number: 7975797
    Abstract: In a configuration in which a rod is extended by an actuator and raises a hood at a time of a collision with a collision body, when a collision load greater than a predetermined value is input to near a hood pushed up area, the collision energy is efficiently absorbed. In a state in which a hood (12) is maintained in a pushed up position, when a collision load equal to or greater than a predetermined value is input from a hood upper side, a distal end portion (54) of a rod (20) slides towards a vehicle rear side along a pushed up surface (38) of a hood rear portion, while deforming the rod (20) by bending, thereby absorbing collision energy. At this time, before a base of a hinge arm (30) contacts a cowl top side (22), distal end portion (54) of rod (20) catches against a bending portion (60) such that rod (20) is bent further.

  • Patent number: 7527121
    Abstract: There is provided a pedestrian protection air bag system M1 in which air bags accommodated on a cowl each have a recessed portion which avoids a hinge mechanism and project from lateral side edges of a lower surface of a hood panel at a rear end thereof so as to cover front sides of front pillars. The hood panel is configured to be raised on a rear end side thereof so as to form a projection space for the air bags between the cowl and the rear end of the hood panel, while when in normal use, the hood panel is made to be opened upwards at a front end side thereof by means of the hinge mechanisms provided near the left and right edges at the rear end thereof. The hinge mechanisms, cases which cover the folded air bags and actuators for raising the hood panel are provided sequentially in that order towards the front on the lateral side edge of the hood panel at the rear end thereof.

  • Patent number: 7207598
    Abstract: In the occupant protection device according to the present invention, a restraint body joined with a driving mechanism is located near a target area of a seated occupant while being surrounded by an interior decoration member. Upon predicting a collision of the vehicle, the driving mechanism is actuated to protrude the restraint body from an opening in the interior decoration member for restraining the movement of the target area upon collision by its side facing the occupant, and when the collision is avoided, the driving mechanism returns the protruded restraint body in the opening of the interior decoration member. The restraint body is provided in the vicinity of its outer periphery with a retaining hole, a clip to be inserted in and retained by the retaining hole, and a guide surface for guiding the clip into the retaining hole for helping the restraint body to return in the opening of the interior decoration member.
