Abstract: A passenger protecting apparatus includes a seat including a seat cushion and a seat back. The apparatus also includes an airbag positioned under a seating surface of the seat cushion; an inflator for producing inflation gas to inflate the airbag. The inflator may be located within the airbag.

Abstract: A seatbelt apparatus is provided which can constrain a passenger by ensuring removal of a slack of a lap belt when two pretensioners are activated under two different time frames. A pretensioner of a seatbelt retractor is activated first, and a shoulder belt and a lap belt are pulled in a direction toward the seatbelt retractor. Subsequently, a pretensioner of a belt anchor portion is activated and pulls a seatbelt toward the belt anchor portion, and hence a one-way tongue catches and locks the seatbelt. Accordingly, the shoulder belt is prevented from moving toward the lap belt through the tongue. Therefore, removal of the slack of the lap belt is ensured, and hence a lumber of the passenger is firmly fixed.

Abstract: A seatbelt webbing includes a shoulder part and a lap part. The shoulder part is a standard belt and at least part of the lap belt is an airbelt. In a front collision, a pretensioner of the shoulder part is activated, thereby retracting a specified length of the seatbelt webbing and tightening the shoulder part. As a result, part of the lap part slides through a hole of a seatbelt tongue toward the shoulder part, thereby correspondingly tightening the lap part. After a lapse of a predetermined period of time, an ignition control unit activates an inflator for the airbelt. Thus, the lap part is pulled and tightened by the inflation of the airbelt. Further, the inflation of the airbelt pulls part of the shoulder part through the hole of the tongue toward the lap part, thereby further tightening the shoulder part.

Abstract: The present invention relates to a passenger protecting device for protecting a passenger in a seat in a vehicle in the event of a collision, and particularly relates to a passenger protecting device having a configuration for restraining the waist of the passenger in a frontal collision so as to prevent forward and backward movement of the body of the passenger. The passenger protecting device may include a bag disposed underneath the front portion of a seat cushion, a gas generator for inflating the bag, a bag envelope disposed so as to surround the bag, and a cover.

Abstract: An inflator having at least first and second gas outputs and configured to generate gas. The inflator releases the gas through the first gas output with a fist gas flow rats and to release the gas through the second gas output with a second gas flow rate different from the first gas flow rate.

Abstract: To simplify the mechanism of an occupant protection system in which a seat bag at the front part of a seat cushion and a lap bag are inflated to protect an occupant and also to simplify the mounting structure of the occupant protection system to a seat frame, a holder is mounted to the side frame of a seat. The holder includes a pretensioner connected to a lap anchor, an inflator for inflating a seat bag and a lap bag, and a manifold for distributing gas from the inflator to the seat bag and the lap bag. The connecting structure of the lap anchor and the pretensioner is of a latch type (insert-lock type).

Abstract: An occupant protection system is provided having a preferable cushion characteristic even at the front part of the seat. In one form, the occupant protection system includes an airbag disposed on S-springs and inflatable to push a seat cushion upward while being supported from below by the S-springs, and a gas generator for inflating the airbag. The airbag extends along the lateral width of the seat, of which the left and right ends are fixed to left and right side frames with bolts, respectively. The airbag is normally disposed on the S-springs in an uninflated state and in a slightly loose state lengthwise. As the seat cushion and the S-springs which support it are moved downward as an occupant sits in the seat cushion, also the airbag can be moved (deformed).

Abstract: An occupant protection system is provided in which parts along the length of the airbag inflate substantially at the same time. The occupant protection system includes an airbag inflatable on a seat pan such that it pushes the front of a seat cushion upward and a gas generator for inflating the airbag. The airbag extends along the lateral width of the seat. The airbag includes a partition panel extending along the length of the airbag therein. In one form, the partition panel partitions the interior of the airbag into a first chamber and a second chamber which extend from one longitudinal end of the airbag to the other end. The gas generator is disposed in the first chamber. The partition panel has communication holes for communicating the first chamber with the second chamber.
