A child seat includes a seat portion, a backrest frame pivotally connected with the seat portion, a front guard extending transversally above the seat portion and having a side end portion pivotally connected with the seat portion, the front guard being rotatable relative to the seat portion between an unfolded position and a folded position, and a folding mechanism including a latch connected with the seat portion, the latch being movable relative to the seat portion and the front guard to engage and disengage the side end portion of the front guard, the latch being engaged with the side end portion for locking the front guard in the unfolded position and disengaged from the side end portion for unlocking the front guard.

A seatbelt device is provided with a webbing and a bag body. The webbing is applied to the body of a vehicle occupant. The bag body includes a first layer at a webbing side and a second layer at an opposite side from the webbing, with the first layer disposed therebetween. The bag body is provided along a length direction of the webbing, fixed to one side of a thickness direction of the webbing and supported by the webbing, and disposed between the webbing and the body of the vehicle occupant in a state in which the webbing is applied to the body of the vehicle occupant. The bag body is inflated by fluid being supplied thereinside. A joined portion at which the first layer and second layer are locally joined together is formed in the bag body. The inflation of the bag body is controlled by the joined portion.

A rear vehicle seat airbag module configured to be mounted to a portion of a seat back of a front vehicle seat comprising an inflator and an inflatable cushion comprising a lower portion, an upper portion and an external tether connecting the lower portion and the upper portion. The inflator provides inflation gas to the inflatable cushion and the inflatable cushion is configured to deploy forward of an occupant seated in a rear seat of a vehicle by curving away from the occupant. The external tether is configured to control a trajectory of the deployment of the inflatable cushion by pulling the upper portion toward the lower portion to curve the inflatable cushion such that the upper portion is located above the lower portion.

Multi-chamber airbag systems for use in aircraft and other vehicles are described herein. In some embodiments, an occupant restraint system includes a multi-chamber airbag that deploys from an occupant restraint (e.g., a lap seat belt) in an aircraft. The multi-chamber airbag can include a first portion that inflates generally upward in front of the occupant's torso, and a second portion that inflates in front of the first portion. The first portion and/or the second portion can include multiple chambers (e.g., generally cylindrical-shaped chambers) that, when inflated, provide the airbag with a shape and/or contact surfaces which can help to maintain the position of the airbag between the occupant and a strike object or hazard. In other embodiments, multi-chamber airbags configured in accordance with the present disclosure can me mounted to a structure (e.g., a monument, console, seat back, etc.) positioned generally in front of the occupant. The structure-mounted airbag can deploy generally toward the occupant in the event of a vehicle impact or other potentially harmful event to protect the occupant from impact injury.

An airbag apparatus may include an airbag module mounted at a lower end portion of a crash pad; an airbag cushion configured to deploy from the airbag module to deploy in a space between a knee portion and a head portion of a passenger, wherein a tether is connected to the airbag cushion in a deployment direction of the airbag cushion toward at least one of the knee portion, a chest portion, and the head portion of the passenger to form an integrated deployment shape of the airbag cushion; and a release device connected to the tether close to the airbag module, and operated to allow the tether to be released or maintained in a fixed state in a deployment process of the airbag cushion depending on a body shape of the passenger on a seat of the vehicle.

A vehicle safety seat system comprises: i) a vehicle seat configured to move to a substantially reclining position, the vehicle seat comprising a seat back and a seat bottom; and ii) a first support arm associated with the seat back, the first support arm including a first airbag on a lower surface of the first support arm, the first support arm holding the first airbag in a position above the thorax of a passenger reclining in the vehicle seat. The first airbag inflates in the event of a collision and provides protection between the first support arm and the thorax of the passenger.

A vehicular airbag device capable of improving reduction of an occupant obstruction value during a diagonal collision. A vehicular airbag device opens an airbag door on an instrument panel. The outer shape of the airbag when fully deployed and expanded is line-symmetrical with respect to a center line of the opening in a vehicle left-right width direction, and a width dimension in the vehicle width direction at a position of a rear edge of the instrument panel in the vehicle longitudinal direction is greater than a width dimension in the vehicle width direction at a position of a center of the opening in the vehicle longitudinal direction which is more forward in the vehicle longitudinal direction than the rear edge position of the instrument panel.

[Problem] To expand and deploy a hood-shaped airbag in a reliably sandwiched condition between the top of a shoulder of a seated occupant and a seatbelt in a normal set condition during a collision, and reduce injury to the occupant by a device other than an airbag such as a seatbelt or the like. [Resolution Means] An airbag device 11 contains an airbag 12 and inflator 13 integrally covering the head 2a and a side portion of a seated occupant 2. The airbag 12 in a flat condition prior to folding has a plurality of chambers 12c demarcated in a longitudinal direction. The chamber 12c has a head protecting chamber 12ca stored in an upper portion of a backrest portion 1b of a seat 1 and a pair of side protecting chambers 12cb stored in opposing positions separated in a vehicle width direction on both left and right sides of the backrest portion 1b. At the time of expansion and deployment, the side protecting chamber 12cb expands and deploys between the seatbelt 3 and occupant 2, and thus the airbag 12 is configured such that a space S is formed between the occupant 2 and airbag 12 deployed at a position where the seatbelt 3 passes.

A child seat includes a front guard and a backrest frame respectively connected pivotally with the seat portion about a first and a second pivot axis, and a folding mechanism including a latch pivotally connected with the seat portion about a third pivot axis for locking and unlocking the front guard with respect to the seat portion, and a linking part coupled to the latch and pivotally connected with the backrest frame about a fourth pivot axis. A rotation of the backrest frame from a deployed position toward a collapsed position causes a displacement of the linking part that urges the latch to unlock the front guard. The first, third, second and fourth pivot axes are arranged in that order along a direction from a front to a rear of the seat portion when the backrest frame is in the collapsed position and the front guard in a folded position.

An occupant protection device which is configured to protect an occupant seated on a seat, includes a seat belt, an airbag, and an inflator configured to supply inflation gas to the airbag. The airbag has a bag shape formed of a flexible sheet body, the airbag is folded and stored in a storage part provided in a lap belt, the airbag is inflated so as to project toward a front upper side when the inflation gas flows into the airbag, and the airbag has a substantially triangular prism shape whose axial direction is substantially aligned with a left-right direction so as to include a leg abutting surface which is capable of abutting an upper surface of a leg of the occupant and an upper body restraining surface which is capable of restraining the occupant from a chest to a head, when the airbag is completely inflated.
