Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Example 1
As shown in fig. 1 to 6, the airbag for protecting a passenger in a passenger seat according to the present invention includes an airbag 1 formed by sewing an upper sheet 102, a lower sheet 101, and two side sheets 103 located at both sides with a sewing thread, wherein upper and lower ends of the upper sheet 102 correspond to upper and lower ends of the lower sheet 101 and are connected by sewing with the sewing thread. A mounting hole 101a is provided in the middle of the lower plate 101 for mounting the gas generator. An exhaust hole 103b is provided on each of the two side panels to facilitate adjustment of the pressure of the airbag 1 after deployment.
The edges of the two sides of the upper piece 102 and the corresponding connection parts on the side pieces are respectively provided with a convex part 102a and a convex part 103a, the convex parts are approximately trapezoidal, two vertex angles are in round corner transition, the convex parts 102a on the two sides of the upper piece and the edges of the convex parts 103a corresponding to the side pieces 103 are sewn through sewing threads, so that a central protection area and two convex areas 110 positioned on the two sides of the central protection area are formed for passengers after the air bag is unfolded.
Two Z-shaped folding structures 102b are symmetrically arranged on the inner sides of the convex parts on the two sides of the upper sheet 102, and after the air bag is inflated, the size of the inner side surface of the convex area can be prolonged by stretching the folding structures 102b, so that the convex area is expanded towards the two sides, and the expansion thickness of the convex area is increased.
The folding structure 102b is a multi-layer cloth structure formed by folding the upper piece along the folding line in a Z shape, and the length of the inner side surface of the convex area can be adjusted by changing different folding widths, so that the unfolding angle of the convex areas on two sides of the air bag can be adjusted. In this embodiment, the folding structure 102b is a three-layer cloth structure formed by folding the upper piece along two folding lines, and the folding width W of the folding structure 102b is 20-60 mm.
Two obliquely arranged side pull belts 104 are symmetrically arranged in the air bag, one ends of the side pull belts 104 are respectively connected to sewing tracks 103c in the middle parts of the two side pieces, and the other ends of the side pull belts 104 are respectively connected to sewing tracks 102c of the innermost cloth pieces of the folded structure 102b on the same side of the upper piece; for controlling the deployed length and deployed width of the air bag and the deployed thickness of the raised regions, while controlling the deployed angles of the two raised regions. A waist-shaped hole is respectively arranged on the side pull belts 104 for reducing the weight of the product.
Alternatively, the other ends of the side pull tapes 104 can be respectively connected to the sewing tracks of the innermost cloth of the folded structure 102b at the other side of the upper panel, so that the two side pull tapes 104 are arranged crosswise in an X shape, thereby better controlling the unfolding width of the air bag.
As shown in FIG. 7, when the airbag is inflated and deployed, point C is the connecting position of the side pull strap 104 on the upper panel, the distance from point C to point D is the length of the inner side of the raised area, i.e. the width of the raised portions on both sides of the upper panel, and the deployment angle between the two raised areas 110 when the folded structure 102b is not extended is a, as shown by the broken line in FIG. 7. When the folded structure 102b is extended by inflating the airbag, the distance between the point C and the point E is the length of the extended folded structure 102b, and the length CD' of the inner side of the convex area is CD + CE; the unfolding angle between the two convex areas 110 is changed from a to b, so that the convex areas are expanded towards two sides, the unfolding angle between the two convex areas 110 is increased, and the protection range of the air bag is expanded; while also increasing the deployed thickness of the raised region.
Example 2
As shown in fig. 8 to 11, the airbag for protecting a passenger in a passenger seat according to the present embodiment includes an airbag 1 formed by sewing an upper sheet 102, a lower sheet 101, and two side sheets 103 located at both sides with sewing threads, wherein a longitudinal pull tape 105 is provided in the airbag, one end of the longitudinal pull tape 105 is provided with a through hole 105a, the through hole is overlapped with a mounting hole in the middle of the lower sheet and then sewn on a sewing track 105c around the mounting hole, the other end of the longitudinal pull tape 105 is sewn and fixed on a sewing track 105b in the middle of the upper sheet, so that the longitudinal pull tape 105 extends in an airbag deployment direction, and the deployment length of the airbag and the deployment angle of the protruding regions at both sides of the airbag can be controlled by the longitudinal pull tape 105.
Other structures of this embodiment are the same as those of embodiment 1, and are not described again in this embodiment.
As shown in fig. 12, the airbag of the present invention is folded and the gas generator 2 is disposed inside the instrument panel 3, when the vehicle collides, the gas generator 2 receives the collision signal and inflates the airbag 1, and after the airbag 1 inflates and expands, an air cushion is formed between the windshield 4 and the instrument panel 3 to support the head 5 of the occupant.
When a vehicle is involved in a frontal collision, a small offset collision or an oblique collision, an occupant moves in trajectory directions of different angles under the action of inertia, and the effect of the airbag on protecting the occupant will be described below from different movement trajectories of the occupant.
When the head 5 of the occupant first contacts the airbag, as shown in fig. 13 and 14, when the occupant moves at 0 ° and a small angle c, the head 5 of the occupant may contact only the middle region of the upper sheet 102 or simultaneously the folded structure 102b, the airbag has sufficient support for the occupant, and there is a certain limit to the deflection of the head.
As shown in fig. 15, when the occupant moves at a large angle d, the head 5 of the occupant contacts the inner side surface of the airbag convex region, i.e., the convex portion 102a, and the head 5 of the occupant is supported by the airbag 1 in the moving direction, and the curtain airbag 6 is supported by the head, so that the head 5 of the occupant does not slip off.
When the head 5 of the occupant first contacts the curtain airbag 6, as shown in fig. 16, when the occupant moves at a larger angle f, the head 5 of the occupant first contacts the curtain airbag 6 because the B-pillar end of the curtain airbag 6 is thick, and the head 5 of the occupant hits the inner side surface of the convex region of the airbag under the reaction force of the curtain airbag 6, and the airbag sufficiently supports the head 5 of the occupant.
While the embodiments of the invention have been disclosed above, it is not limited to the applications listed in the description and the embodiments, which are fully applicable in all kinds of fields where the invention is suitable, and further modifications may readily be made by those skilled in the art, and the invention is therefore not limited to the specific details without departing from the general concept defined by the claims and the scope of equivalents.
