  • Patent number: 9469269
    Abstract: A passenger retaining apparatus includes a driver seat airbag and a curtain airbag. The curtain airbag includes first and second inflation portions and a recess portion. The first inflation portion is inflated at a passenger side with respect to the inflated driver seat airbag in a vehicle body longitudinal direction. The second inflation portion is inflated at a wind shield side with respect to the inflated driver seat airbag in the vehicle body longitudinal direction. The recess portion is formed between the first and second inflation portions to engage with the inflated driver seat airbag. The driver seat airbag retains a front surface of a head of the passenger and the first inflation portion retains a side surface of the head of the passenger.

  • Publication number: 20130062868
    Abstract: An acceleration sensor (40R) for detecting a side surface collision which occurs in a vehicle is mounted on a beam (112) of a door via a support member (50). When a force due to a collision acts on the beam (112), this force is dampened by the support member (50) and thereafter transmitted to the acceleration sensor (40R). As a result, even if the beam (112) moves at an acceleration exceeding the rated input of the acceleration sensor (40R), the acceleration of the acceleration sensor (40R) is suppressed to a level not greater than the rated input. Accordingly, the side surface collision can be detected with high accuracy without using a sensor having a high rated input.

  • Patent number: 8292324
    Abstract: A side impact crash sensor that operates in conjunction with displacement of a door outer panel of a vehicle door in the event of a side impact crash. The side impact crash sensor comprises a sensor housing coupled to a vehicle door member in a sectioned region of the door and a pendulum rotates around a rotating shaft secured to the sensor housing in the event of a side impact crash. The pendulum is conductive and is housed in a housing space of the sensor housing. The side impact crash sensor further comprises a detecting section including a conductive coil energized by an alternating current secured to the sensor housing. The detecting section detects a rotation operation mode of the pendulum on the basis of a change in impedance of a conductive coil which occurs in conjunction with a rotation operation of the pendulum.

  • Publication number: 20120256405
    Abstract: A control device is provided with a first collision determiner for determining a side collision to a vehicle based on velocity in a direction orthogonal to the advancing direction of the vehicle, and a second collision determiner for determining a side collision to the vehicle based on a displacement amount and displacement velocity of an acceleration sensor provided in a door of the vehicle. When the vehicle is traveling at a relatively high velocity, the control device detects a side collision to the vehicle using the determination result of the first collision determiner and the determination result of the second collision determiner. In addition, when the vehicle is traveling at a low velocity or is stopped, the control device detects a side collision to the vehicle using the determination result of the first collision determiner, without using the determination result of the second collision determiner.
