A vehicle side curtain airbag device having front protection function, comprising a side airbag (1) and an auxiliary airbag (2) connected to one side surface of the side airbag (1) and arranged in a left/right transverse direction after being expanded; a dividing hole membrane (3) is disposed between the side airbag (1) and the auxiliary airbag (2); the dividing hole membrane (3) is ensured to be opened only when the internal pressure of the side airbag (1) reaches a certain value, thus realizing self-adaptive opening threshold adjustment, controlling the instant of inflation and inflation speed of the auxiliary airbag (2), and adjusting the stiffness of the auxiliary airbag (2). When a vehicle has a collision, the device protects the head and neck of a passenger in both side collision and front collision traffic accidents, thus effectively absorbing the collision impact energy of the passenger, and reducing injury to the passenger.

A bumper reinforcement includes a body portion joined to a vehicle body front end portion through portions of the body portion on a first direction side and a second direction side in the vehicle width direction, and a reinforcing member joined to the body portion along the body portion. The body portion includes a first standard rigidity region, a high rigidity region, and a second standard rigidity region arrayed next to each other in this order in the vehicle width direction. The high rigidity region has rigidity higher than rigidity of the first standard rigidity region and rigidity of the second standard rigidity region and is positioned in a center of the body portion in the vehicle width direction. The reinforcing member is provided so as to at least partially overlap the high rigidity region and the first standard rigidity region through a first boundary position.

A front airbag apparatus for a vehicle may include an airbag chamber including front panels, and internal tethers connecting the front panels of the airbag chamber to an airbag housing and dividing the airbag chamber into a plurality of sections, in which lengths of the internal tethers may be smaller than a length of the airbag chamber in a front-rear direction of the vehicle, and when the airbag chamber is fully inflated, joints of the internal tethers on the front panels may be recessed, whereby the front panels may form a prominence-depression shape.

A pre/post-tensioning controller system for a wheelchair tie-down and occupant restraint system (“WTORS”) will be a comprehensive energy management system for controlling excessive excursions of a wheeled mobility device during various adverse driving scenarios. The system uses multiple pre-tensioning and post-tensioning events during a front, side, or rear impact crash or rollover scenario—and effectively controls excursions by the tensioning of the WTORS equipment at specific and ideal moments. The system also uses tensioning events on the tie-down equipment during a long duration turn or other aggressive maneuvers. The system may also use tensioning events on the occupant restraints. The energy management system can be adapted for use with traditional four-point tie-downs and newer three- and two-point tie-down systems that incorporate fixed or movable bumpers, as well as compressive-type securement systems, and other systems as well, including docking systems.

An airbag is configured by six base materials of two side wall configuration panels, a projecting portion configuration panel, a front panel, and two rear panels. Each of the side wall configuration panels configure a left wall portion or a right wall portion facing each other on a side in a rightward-leftward direction in a main body inflation portion, and a projecting portion configuration portion configuring a projecting inflation portion is located in one of the side wall configuration panels. The front panel configures a region from an upper wall portion to a lower wall portion, which face each other on a side in an upward-downward direction in the main body inflation portion. Each of the rear panels configures a rear surface in the main body inflation portion when the main body inflation portion is completely inflated. The projecting portion configuration panel has an external shape substantially coincident with that of the projecting portion configuration portion. The projecting portion configuration panel and the rear panel on the projecting inflation portion side include a recess portion configuration portion configuring a restraining recess portion.

A vehicle includes a hood at a front end, a frunk under the hood, and a cabin. The vehicle includes a cross-beam positioned between the frunk and the cabin, and configured to inhibit protrusion of the frunk into the cabin in a frontal impact. The vehicle also includes a frame and the cross-beam is coupled to the frame. The cross-beam is a unitary member that is coupled to the frame or the cross-beam includes two members separated by a gap and each member is coupled to the frame. The frame includes shock towers for coupling the cross-beam to the frame. The frame can also include a bracket for coupling the cross beam to the frame.

The present disclosure relates to a method for imaging an optical signal received by a graded index (GRIN) optical element to account for known variations in a graded index distribution of the GRIN optical element. The method may involve using a plurality of optical detector elements to receive optical rays received by the GRIN optical element at a plane, where the plane forms a part of the GRIN optical element or is downstream of the GRIN optical element relative to a direction of propagation of the optical rays. The optical rays are then traced to a plurality of additional specific locations on the plane based on the known variations in the graded index distribution of the GRIN optical element. A processor may be used to determine information on both an intensity and an angle of the received optical rays at each one of the plurality of specific locations on the plane of the GRIN optical element.

A passenger seat airbag device includes an airbag including a front collision restraining surface, and an oblique collision restraining portion including a protruding portion in which a surface is set as an oblique collision restraining surface, and a restraining recess portion whose facing surfaces are able to restrain the head of the occupant. The rear wall main portion has the front collision restraining surface. The rear wall end edge portion has the oblique collision restraining surface. The upper edge of the rear wall end edge portion is coupled to a rear edge of the upper wall portion. The lower edge of the rear wall end edge portion is coupled to a rear edge of the lower wall portion. An entire edge of the separation edge of the rear wall end edge portion is coupled to a rear edge of the rear edge side portion.

A steering wheel airbag, arranged to cover a steering wheel when inflation is completed, includes: a front-collision receiving surface which is arranged on a side of a driver when inflation is completed, so as to receive the driver moving forward during a head-on collision of a vehicle, the front-collision receiving surface being arranged substantially along a vertical direction to be tilted with respect to a ring surface of the steering wheel when inflation is completed; and arm restraining parts which are arranged near arms of the driver steering a ring part of the steering wheel on both right and left sides of the front-collision receiving surface when inflation is completed, the arm restraining parts coming into contact with the arms during an oblique collision or an offset collision of the vehicle, so as to prevent a movement of the driver to an obliquely front side.

A vehicle pedal arrangement according to one embodiment includes a support, a rotating shaft, a pedal that is pivotable with respect to the rotating shaft, a retention member and actuating means. The pedal includes a retaining housing and an opening, such that under normal operating conditions the rotating shaft is arranged in the opening and the retention member is at least partially housed in the retaining housing supported against the rotating shaft, retaining the rotating shaft in the opening. In the event of a head-on collision, the actuating means moves the retention member such that the pedal is no longer retained against the rotating shaft.
