An apparatus for dynamically tilting a seatpan in an aircraft passenger seating assembly includes a seat frame, seatback, seat cushion, and cushion support structure (e.g., a seatpan), the seat cushion and seatpan together having a forward end and a rear end and together supporting a passenger occupying the seating assembly. Accelerometers may detect an inertial event such as a rapid deceleration that may cause the passenger to pitch forward; dynamic seatpan actuators (e.g., airbags or ballistic devices) connected to the accelerometers react to the inertial event by detonating, driving the seatpan and seat cushion upward. As a result, the head path of the passenger may be redirected upward, alleviating the risk of passenger injury and component damage. Additional airbags may react to the inertial event by tightening the passenger seatbelt.

Problem:

To more effectively restrict movement of the airbag in an expanded and deployed state in the event of a vehicle collision, and improve the performance of restraining a passenger using an airbag.

Resolution Means:

A passenger restraining device of the present invention is provided with an airbag and tensile cloth. The tensile cloth is deployed to the outside of a seat by expansion and deployment of the airbag, and pulled from an upper surface of a seat back portion to a seat cushion portion. When the airbag is viewed in plan view from above during the expansion and deployment, of four regions demarcated by a first imaginary line extending in a front-rear direction of a vehicle through a center of a widest portion of the airbag on a straight line parallel to a left-right direction and a second imaginary line orthogonal to the first imaginary line and extending in the left-right direction through a center of the first imaginary line in a front-rear length of the airbag, the tension cloth passes through at least a region on an opposite side of the first imaginary line from the passenger and a vehicle front side of the second imaginary line.

An airbag operating apparatus for a vehicle may include: a sensing signal input unit configured to receive a sensing signal; a plurality of squib driving units including input ports connected in parallel to one another, having internal resistances set different from one another, installed to correspond to a plurality of airbags, respectively, and configured to drive the corresponding airbags when reaching an ignition current value according to airbag deployment signals; a storage unit configured to store the internal resistances of the plurality of squib driving units and output voltages of the airbag deployment signals according to deployment situations; and a control unit configured to receive the sensing signal from the sensing signal input unit, determine situations for deploying the plurality of airbags, and output the airbag deployment signals as output voltages to the input ports of the plurality of squib driving units according to the determination result.

An airbag device includes an airbag, an airbag case that is made from metal and includes a base wall and a tubular wall, and an airbag cover that is made from synthetic resin and includes a covering wall and a joint wall. The case and cover are coupled together by insertion of hooks of the tubular wall of the case into joint holes of the joint wall of the cover. An approximation-limiting region suppresses the cover as coupled with the case from moving further towards the base wall of the case, and a separation-limiting region suppresses the cover as coupled with the case from moving further away from the base wall of the case. The approximation-limiting region includes an abutment region and a receiving region engageable with the abutment region. The separation-limiting region includes a retaining hole and a projection engageable with an inner surface of the retaining hole.

A vehicle occupant restraint device comprises a control unit and a group of at least two matched airbags (20, 24; 22, 26) for the protection of a vehicle occupant (10; 16) on a particular vehicle seat (12; 16). The control unit is arranged and the airbags (20, 24; 22, 26) are disposed and designed so that, in a collision case, the control unit differentiates between a first situation in which the vehicle occupant (10; 16) is located in a standard distance area relative to a first airbag (20; 22) and a second situation in which the vehicle occupant (10; 16) is located in a rear area which is further distant from the first airbag (20; 22) than the standard distance area. When the first situation is given, the control unit activates the first airbag (20; 22) only. In contrast, when the second situation is given, the control unit activates the first airbag (20; 22) and additionally at least a second airbag (24; 26) of the group, with the first airbag (20; 22) backing the second airbag (24; 26).

Provided is an airbag which further reduces the degree of injury to a vehicle occupant while also exhibiting sufficient occupant protection performance using less output from the inflator, by both preventing airbag internal pressure from rising excessively when making contact with the occupant and increasing the speed of deployment in an occupant-protection area. This hollow-weave airbag has an opening in a main chamber that inflates for the purpose of occupant protection, a structure wherein a first yarn extending separatingly from a first fabric layer of the opening to a non-inflating portion is caught on a float yarn extending on the inside of a second fabric layer and subsequently caught on a float yarn extending on the inside of the first fabric layer, this structure being repeated at least once and forming a pair with another structure wherein a second yarn extending separatingly from the second fabric layer of the opening to the non-inflating portion is caught on the float yarn extending on the inside of the first fabric layer and subsequently caught on the float yarn extending on the inside of the second fabric layer, this structure being repeated at least once.
