Disclosed is a side airbag, located between adjacent seats after being deployed. The side airbag includes a first air chamber (1), a second air chamber (2), and a third air chamber (3). The first air chamber (1) is located between the second air chamber (2) and the third air chamber (3). The second air chamber (2) is deployed toward one of the adjacent seats. The third air chamber (3) is deployed toward the other of the adjacent seats. The first air chamber (1) includes a primary air chamber (11) and a secondary air chamber (12). The primary air chamber (11) is deployed toward a front of a seat. The secondary air chamber (12) is deployed toward a rear of the seat. Further disclosed is a seat. The first air chamber (1) is provided as the primary air chamber (11) extending forward and the secondary air chamber (12) extending rearward, thereby increasing the coverage of the first air chamber (1). Whether the seat is adjusted forward or rearward along a slide rail, an occupant can be protected.

A safety airbag (1). The safety airbag (1) is configured to be mounted at the roof of a vehicle, and includes: an airbag (10), having a deployed state and a stowed state; and a gas generator, configured to inflate the airbag (10) to cause the airbag (10) to expand into the deployed state. The airbag (10) includes a top panel (111), and the top panel (111) is positioned at the roof of the vehicle in the deployed state. The airbag (10) further includes a tether (13) located on an inner side of the airbag (10), the tether (13) and the top panel (111) being abutted against each other. The top panel (111) is provided with a first pressure relief port (113), and the tether (13) is provided with a second pressure relief port (121). The first pressure relief port (113) and the second pressure relief port (121) are aligned with each other in a first time period during a deployment process of the airbag (10), and the first pressure relief port (113) and the second pressure relief port (121) are staggered with each other via a telescopic portion (111A) provided on the top panel (111) in a second time period during the deployment process of the airbag (10), wherein the second time period is later than the first time period.

A front passenger airbag, comprising an airbag body (10). The airbag body (10) comprises: a first cut piece (11), a second cut piece (12), and a middle cut piece (13), provided with a first end (131) and a second end (132) along a travel direction of a vehicle, and provided with a first side (133) and a second side (134) along a direction transverse to the travel direction of the vehicle, wherein side edges of the first side (133) and the second side (134) of the middle cut piece (13) are sewn and connected along peripheral edges of the first cut piece (11) and the second cut piece (12), respectively; the length of each of the peripheral edges of the first cut piece (11) and the second cut piece (12) is greater than the length of each of the side edges of the first side (133) and the second side (134) of the middle cut piece (13), so as to form an empty peripheral edge (14) that is not sewn and connected to the side edge of the middle cut piece (13), and as the first end (131) and the second end (132) of the middle cut piece (13) are sewn, the empty peripheral edge (14) is folded in half and then sewn to form a pointed side ear portion (15). A vehicle, which has the front passenger airbag. With this arrangement, pointed side ear portions are formed through cutting shapes and sewing manners of the first cut piece, the second cut piece and the middle cut piece, and an internal tether or an external tether does not need to be provided, thereby reducing manufacturing costs.

Provided in the present invention is a buckle assembly. The buckle assembly includes a buckle, a tongue, and a Hall assembly configured to detect whether the tongue is inserted into the buckle. The Hall assembly is fixed into an inner cavity of the buckle, and includes a chip, a magnet, and a housing, and the chip and the magnet overlap and are spaced apart in a predetermined direction. The housing includes a first positioning portion configured to position the chip at a first position and a second positioning portion configured to position the magnet at a second position. The first positioning portion includes a cover, a base, and a first snap-fit member rotatably connected to one of the two. The cover and the base define a first accommodating space configured to accommodate the chip. When the first snap-fit member rotates to a first rotation position, the first accommodating space is opened. When the first snap-fit member rotates to a second rotation position, the first snap-fit member applies a force to a first side surface of the chip, to enable a second side surface of the chip opposite to the first side surface to abut against a first stopper provided on the first positioning portion.
