An airbag includes an upper portion and a lower portion. The upper portion is for extending from a vehicle roof and engagement with a head rest of a seat in an inflated position. The lower portion forms a cushion board that extends downwardly from the upper portion for engagement with and disposition between a seatback and a restraining bar located rearward of the seatback in the inflated position.

A deployable containment system of a vehicle includes a pair of guide channels that surround an opening facing one of a forward direction of travel of the vehicle and a backward direction of travel of the vehicle. Each of the guide channels has a first end and a second end. A housing is mounted to the first ends of the guide channels. A shield is configured to: deploy from the housing; travel along the guide channels toward the second ends of the guide channels; and cover at least a portion of the opening, An actuator is configured to, in response to being triggered, deploy the shield from the housing and move the shield along the guide channels toward the second ends of the guide channels.

A vehicle seat structure that includes: a seatback that is provided at a seat rear side of a seat cushion so as to be able to tilt in a seat front-rear direction with respect to the seat cushion, and that can support an upper body of a vehicle occupant; a headrest that is provided at a side of the seatback, which side is opposite from a side at which the seat cushion is located, and that can support a head portion of the vehicle occupant; and shoulder restraining portions that are provided at the headrest or at the headrest side of the seatback, and that, by protruding out toward a vehicle occupant side at a time of an emergency of a vehicle, restrain both shoulders of the vehicle occupant in a case in which the vehicle occupant has moved along the seatback toward the headrest side.

A vehicle includes a surrounding information detector detecting at least one of a position and a speed of an object around the vehicle including a vehicle ahead and a vehicle behind, a vehicle information sensor detecting at least one of a speed and an acceleration of the vehicle, a brake module generating a braking force to decelerate the vehicle, and a controller configured to determine probabilities of a forward collision and a rear-end collision based on output of the surrounding information detector and the vehicle information sensor, determine target forward and rear collision speeds to minimize a sum of injuries to an occupant by the forward collision and injuries to the occupant by the rear-end collision upon determination that there is the probabilities of the forward collision and the rear-end collision, and control the brake module based on the target forward collision speed and the target rear-end collision speed.

An active seat belt control apparatus is controlled according to a state of a vehicle. A control method for the active seat belt control apparatus includes: collecting, by a communication unit, state information about the vehicle; determining, by a controller, whether to activate a pulling operation of a seat belt using the collected state information; and activating the pulling operation of the seat belt using a motor.

A vehicle power supply system is provided for an electric vehicle. The vehicle power supply system has a first relay and a second relay, which are two-contact movable relays that connect/disconnect a high voltage circuit. The first relay has a first movable contact that is arranged to move with respect to a first fixed contact in a first direction when connecting/disconnecting. The second relay has a second movable contact is arranged to move with respect to a second fixed contact in a second direction when connecting/disconnecting. The second direction is opposite to the first direction. One of the first and second relays is oriented such that its movable contact separates from its fixed contact in a direction in which the greatest acceleration input is applied at the time of a collision.

Method and apparatus are disclosed for monitoring windshield vibrations for vehicle collision detection. An example vehicle includes a windshield, a vibration sensor coupled to the windshield to detect window vibrations of the windshield, a first accelerometer to detect vehicle body vibrations of a vehicle body, and a restraint control module. The restraint control module is to detect an event based upon the window vibrations and determine whether the event is a collision event or a non-collision event responsive to comparing the window vibrations and the vehicle body vibrations.

A vehicle seat to be mounted on a vehicle includes a seat cushion and a seat surface lowering mechanism. The seat cushion includes a seat surface on which a waist of an occupant of the vehicle is to be placed. The seat surface lowering mechanism is configured to lower the seat surface in response to either one of an occurrence of a rear-end collision of the vehicle or a sign of the occurrence of the rear-end collision.

A trailer hitch cover assembly, which includes an inflatable object capable of withstanding about 2000 pounds per square inch internal pressure, a first attachment plate disposed within the inflatable object, a second attachment plate disposed in physical contact with but external to the inflatable object, a housing comprising a plurality of threaded apertures extending therethrough and dimensioned to be received by a trailer hitch receiver, where a corresponding plurality of threaded members are attached to the first attachment plate, extend outwardly from the first attachment plate through a surface of the inflatable object, extend through the second attachment plate, and intermesh with the plurality of threaded apertures.

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.
