  • Publication number: 20090302644
    Abstract: The present invention provides a hood impact absorbing apparatus capable of further mitigating an impact that a collision body receives from a hood than ever, wherein a push-up rod pushes up the rear end of a hood at the time of a collision of a vehicle, and when a collision body is battered against the top surface of the hood in this state, the rear end of the hood descends and the distal end of the push-up rod slidingly contacts and moves a rear-side flat portion and an arm intermediate curved portion in the rear end of the hood, and herein, a slide contact angle (?) in the arm intermediate curved portion is larger than a slide contact angle (?) in the rear end of the rear-side flat portion, thereby, during a process in which the rear end of the hood descends, peaks at which an absorbing amount of impact energy becomes large can be provided at least twice, and as a result, the impact can be mitigated further than ever.

  • Publication number: 20090266638
    Abstract: When activated, an actuator causes a piston rod in a cylinder to move forwards so as to support a receiving member for receiving an object to be protected. A lock mechanism for restricting a backward movement of the piston rod includes a lock ring which is accommodated in an accommodating groove on a piston portion and a locking stepped portion on the cylinder side. The locking stepped portion includes a locking and restricting surface and an outer circumferential restricting surface.

  • Publication number: 20090242308
    Abstract: A pedestrian protection system is mounted in the front portion of a vehicle, and includes a controller, a forward movement holding mechanism controlled in actuation by the controller, and a contact body that a pedestrian can contact. The controller, when having predicted a collision of a pedestrian with the vehicle based on a signal from a collision predicting sensor, actuates the forward movement holding mechanism to cause a forward movement of the contact body, and based on a signal from a turn sensor when the forward movement holding mechanism carries out an upward rotation or a downward rotation at the time of contact of the forwardly moved contact body with a pedestrian, controls actuation of the restraint body so as to correspond to a pedestrian moving to a front upper side of the vehicle and a pedestrian moving to a front lower side of the vehicle, respectively.

  • Publication number: 20090243268
    Abstract: The occupant protection system includes a catching body that is housed in a housing located between a near-by seat and a distant seat for upward deployment and a support body that supports the catching body. The catching body covers the impact side of a distant-side occupant to catch the occupant moving toward the impacted lateral and includes a distal end acting as a free end swingable in a left and right direction. The support body is located on a side of the near-by seat close to the impacted lateral for deployment to support the catching body when the catching body swings toward the impacted lateral after receiving the distant-side occupant.

  • Publication number: 20090223360
    Abstract: An actuator includes a cylinder, a piston rod which moves forwards within the cylinder and a lock mechanism for restricting a backward movement of the piston rod that has moved forwards. The piston rod includes a piston portion and a support rod portion which is made to extend from the piston portion. The lock mechanism includes an annular elastic element which is disposed with an inner circumferential edge made to project further radially inwards than an inner circumferential surface of the cylinder and a groove which is disposed so as to extend along an outer circumferential surface of the piston portion for the annular elastic element to be fitted therein.

  • Publication number: 20090145681
    Abstract: The invention provides an actuator A configured as an actuator in which a piston 38 disposed in a cylinder 21 is moved together with a supporting rod 45 connected to the piston 38 by introducing a working fluid G into the cylinder 21 and including a locking mechanism R for restricting a reverse movement of the supporting rod 45 which has moved forwards. The locking mechanism R includes a locking pin 43 adapted to project from an outer circumferential surface of the piston 38 which extends around an axis thereof, a flow path 40 which allows a working fluid G which flows into the cylinder 21 to flow, and a locking surface 25 for locking the locking pin 43 and is made to cause the locking pin 43 to project from the outer circumferential surface of the piston 38 by making use of the pressure of the working fluid G which is allowed to flow into an accommodating recessed portion 39 of the locking pin 43 via a flow path 40.

  • Publication number: 20090127016
    Abstract: A hood panel is arranged in a front end side of a vehicle so as to cover an engine room from above. An air bag system according to the invention includes an air bag which is disposed in a containing part near a front fender which is arranged at an end edge of the hood panel in a lateral direction, so as to cover the substantially entire area in a longitudinal direction of the front fender from above when the air bag has been completely inflated, and an inflator for supplying an inflating gas to the air bag. The air bag has a body part for covering the front fender from the above, and a flow inlet connected to the inflator. The flow inlet is provided in a frontward region of the body part forward from a center in the longitudinal direction in the completely inflated state.

  • Publication number: 20090084620
    Abstract: An actuator AE1 includes a lock mechanism R1 configured to fill a gas G generated by operating a gas generator 35 at inside of a cylinder 22 and moving forward a piston 38 along with a support rod 40 for restricting a rearward movement of the support rod moved forward. The support rod 40 is arranged to be able to absorb a kinetic energy of a protection object person and capable of being plastically deformed when the protection object person is received by a receiving member after having been moved forward. A lock mechanism R1 is constituted by a diameter enlarging deformed portion 42 arranged at a piston and a locking stepped portion 24 capable of restricting the rearward movement of the piston.

  • Publication number: 20070292726
    Abstract: A fuel cell system of the present invention includes a fuel cell stack, a fuel system for supplying a fuel gas to the fuel cell stack, and on-off valves which form a closed space not including the fuel cell stack in the fuel system. The closed space is filled with an inspection gas from the on-off valve which functions also as an inspection gas inlet port. After completion of the inspection, the inspection gas in the closed space is discharged from the on-off valve which functions also as an inspection gas outlet port.
