The present invention relates to a seat airbag for a vehicle in which a cushion storage space 810 capable of accommodating a front cushion 200 is provided at a front end 720 connected to the front cushion 200 in a side cushion 100, and the front cushion 200 folded in a bellows type is inserted and accommodated into the cushion storage space 810. The side cushion 100 and the front cushion 200 can be deployed sequentially with a time difference, so that the reliability of the cushion deployment can be secured.

Techniques for controlling a protection apparatus are provided. An example method includes detecting an offset collision or diagonal collision, and activating a suitable protection apparatus for protecting the side or head of a passenger at a timing in accordance with the degree of collision. An example controller may include a level calculation part for calculating a level of a front face collision, a ΔV.sub.offset calculation part for making an offset adjustment of a speed (ΔV), and a determination part for determining an offset collision or diagonal collision based on the level of the front face collision and the ΔV.sub.offset.

A vehicle and control method include: a seat; an image acquirer to acquire an image of the seat; a first type of roof airbag module in a fixed position in a first area of a headlining; a rail member in a second area of the headlining in a left-right direction of a vehicle body; a second type of roof airbag module in the rail member and movable in left and right directions along the rail member; an angle detector to detect a rotation angle of the seat; and a controller. The controller identifies the seat rotation angle based on the image of the seat and controls activation of at least the first type of roof airbag module or the second type of roof airbag module based on at least the seat rotation angle based on the image of the seat or detected by the angle detector.

A safety system and control method for a pneumatic seat of a vehicle, and a computer-readable medium, the pneumatic seat (10) including a plurality of airbags (101, 102, 103, 104, 105, and 106) corresponding to body parts of an occupant, an information collection module, an information integration module (3), and a control module (4), where the information collection module is configured to collect vehicle body data, motion information, and external environment information of the vehicle, the information integration module (3) is configured to determine a current working scenario of the vehicle based on the vehicle body data, the motion information, and the external environment information; and the control module (4) is configured to inflate a seat cushion airbag (105) when it is determined that the current working scenario is a first working scenario, so as to partially deploy the seat cushion airbag (105); and is configured to fully inflate and deploy the seat cushion airbag (105) when it is determined that the current working scenario is a second working scenario.

An airbag device including: a folded airbag; an attachment member configured to house the folded airbag and to be fixed to the vehicle; and an airbag lid including a main body portion and a protruding support portion. The main body portion is connected to the attachment member in a state of covering the folded airbag from a side opposite to the attachment member. The protruding support portion protrudes from the main body portion. At least a part of the protruding support portion is covered by the trim. The protruding support portion includes: a base end side edge portion joined to the main body portion; a tip end side edge portion provided on a side opposite to the base end side edge portion; a locking portion attaching to the trim; and a reinforcing portion provided continuously along the tip end side edge portion.

An occupant protection system for protecting a vehicle occupant sitting in a seat includes a seatbelt that includes a lap belt for arresting the pelvis of the occupant, and an airbag that is stored in the lap belt. The airbag as deployed includes a main inflatable portion for protecting an upper body of the occupant, and a head protecting portion that is located in a vicinity of an upper end of the main inflatable portion for protecting a head of the occupant. The head protecting portion includes a front inflatable portion for covering a front side of the head, and a pair of side inflatable portions that extend rearward from left and right ends of the front inflatable portion for covering sides of the head. Each of the side inflatable portions is configured to be deployed in such a manner that a space is formed between itself and the head.

A vehicle side airbag device including an inflator, a side airbag, and a duct is installed at a side section on a vehicle width direction outer side of a seatback of a vehicle seat configured to restrain an occupant using a three-point seatbelt. The side airbag receives a supply of gas from the inflator in a vehicle side-on collision. As a result, a waist chamber is inflated and deployed from a lower portion of the side section toward a side of a waist of the occupant, and a head chamber is inflated and deployed from an upper face side of the side section toward a side of a head of the occupant. The duct extends along a vertical direction of the side airbag inside the side airbag, and is configured to guide gas from the inflator into the waist chamber and into the head chamber.

The present invention relates to an airbag apparatus for a vehicle. In order to attain the purpose, the airbag apparatus for a vehicle according to the present invention comprises: a mounting board positioned in front of a rider; and an airbag module which is installed on the mounting board and, when a vehicle collides, restrains and protects the rider by means of inflating and expanding an airbag cushion toward the rider. Therefore, when the vehicle collides, the airbag cushion is inflated and expanded from the mounting board and thus the rider can safely be protected.

An assembly for a vehicle includes a vehicle floor. The assembly includes a pair of vehicle doors spaced cross-vehicle from each other. The vehicle floor is between the vehicle doors. The assembly includes a vehicle seat between the vehicle doors and having a seat bottom supported by the vehicle floor. The assembly includes a pair of inflatable devices that are thermoplastic elastomer and inflatable to inflated positions. The pair of inflatable devices are supported by the vehicle floor and spaced from each other. One of the inflatable devices is between the seat bottom and one of the vehicle doors in the inflated position and the other of the inflatable devices is between the seat bottom and the other of the vehicle doors in the inflated position. The seat bottom is elongated from one of the inflatable devices to the other of the inflatable devices.

An airbag device includes a seat frame that forms a skeleton of a vehicle seat on which an occupant of a vehicle sits; an airbag that is disposed on a backrest portion that supports a back of the occupant in the vehicle seat and that is deployed by supply of gas; and a gas generator that is disposed at a seating surface portion that supports buttocks of the occupant in the vehicle seat and that generates gas to be supplied to the airbag; where a part that is a portion of the seat frame and includes at least a portion of a back frame forming a skeleton of the backrest portion, is formed as a flow tube that connects to the airbag to supply gas generated by the gas generator to the airbag.
