A vehicle side section structure capable of stabilizing the deployment behavior of an airbag that inflates and deploys from a side door toward a vehicle width direction outer side is obtained. An impact beam is attached to a door inner panel. The impact beam includes a support portion that supports an inflator and that includes a side-wall portion disposed at the vehicle width direction inner side of the inflator. Accordingly, reaction force from the deployment of the airbag is able to be supported by the support portion of the impact beam when the airbag inflates and deploys.

A safety apparatus for a vehicle includes a structure, an inflator, a collision position detector, and a deployment controller. The structure extends along an outer periphery of the vehicle, and includes a plurality of partial structures. The inflator is configured to supply gas into the structure. The collision position detector is configured to detect or predict a collision position the vehicle upon colliding against an object The deployment controller is configured to control gas supply from the inflator to the structure, based on a collision position detected or predicted by the collision position detector. The deployment controller causes the inflator to supply the gas to a partial structure corresponding to the collision position to deform at least the corresponding partial structure outward in a vehicle width direction.

A vehicle includes a body portion, an opening defined by the body portion, and an extendable bumper that is positioned in the opening and is moveable with respect to the body portions between an extended position and a retracted position. The extendable bumper includes an inflatable structure that causes movement of the extendable bumper between the retracted position and the extended position in response to inflation and deflation of the inflatable structure.

The present disclosure is directed to a pedestrian protection system that includes a first sensor that generates a first signal indicating a hazard condition in front of a vehicle. The pedestrian protection system may also include an external airbag system that deploys an external airbag outside of the vehicle. In operation, a processor receives the first signal from the first sensor, processes the first signal to detect the hazard condition, and activates the external airbag system in response to the detected hazard condition to protect at least one of a pedestrian and the vehicle.

A shock-absorbing device for vehicles includes a supporting bar, and a gas generator and an airbag arranged on the supporting bar. The airbag includes an inflatable body with a first laminated foil wrapped longitudinally around the inflatable body and a second laminated foil wrapped transversely around the inflatable body. The first and second laminated foils are initially wrapped around the inflatable body in a temporary inflated state of the inflatable body so as to have a length in the respective longitudinal and transverse directions corresponding to the inflatable body in an activated state of the shock-absorbing device.

An airbag apparatus to be applied to a vehicle includes an airbag configured to be deployed forward of a vehicle body front of the vehicle, a collision determiner configured to establish a pre-crash determination in a case where a collision probability with a human body or an object other than a human body is equal to or higher than a predetermined threshold, and an airbag deployment controller configured to deploy the airbag in response to the pre-crash determination. The airbag includes a slit portion formed by recessing a front surface rearward of the vehicle, and branches divided by the slit portion. The airbag apparatus further includes a coupling member configured to couple the branches to each other, and a coupling member disabling unit configured to break coupling of the branches by the coupling member in a case where a collision with the human body is predicted.

A rear collision guard for a vehicle having a battery disposed on an underbody wall that is supported by longitudinal rails. The guard comprises a pair of sidewalls that attach to the longitudinal rails through the underbody wall and extend longitudinally on right and left lateral sides of the battery. A channel is attached to a back-end of each of the sidewalls and is spaced behind the battery. An airbag is attached to a rearwardly facing surface of the channel and is operatively connected to an inflation system that inflates the airbag to expand rearwardly in a rear end collision.

Provided are a method and device for the rear end collision protection of a vehicle. The method comprises: in a driving process of a current vehicle, detecting a rear vehicle distance by a radar; judging whether the rear vehicle distance is less than a distance threshold, and if yes, calculating a collision time according to the approaching speed of the rear vehicle and the rear vehicle distance; and judging whether the collision time is less than a time threshold, and if yes, initiating an airbag disposed at a rear bumper of the current vehicle, wherein after expanded, the airbag forms a long-strip-shaped inflatable bladder at the outside of the rear bumper of the current vehicle.

This patent application discloses a protection system using one of multilayer airbag, expandable pads, and compressed air for moving and flying vehicles and equipments. The multilayer airbag consists of a number of independent airbags within one another which will be inflated with a time sequence or simultaneously. This type of protection system can be used for various moving vehicles and equipment to protect them from any force due to a predicted impact.

A second-time collision position estimator section estimates a second-time collision position that is a position at which an occupant on a two-wheel mobile object has a second-time collision, based on a relative vector estimated by a relative vector estimator section and a first-time collision position identified by a first-time collision position identifier section. An operation instructor section operates an external protection device, which is determined to be able to protect the occupant on the two-wheel mobile object based on the second-time collision position estimated by the second-time collision position estimator section.
