A recovery device for vehicle active airbag airbag

Abstract

The invention discloses a recovering device of a vehicle active safety airbag air pocket. The recovering device comprises the safety airbag air pocket, a pulling belt, a shell body, a shaft sleeve, a base, a rolling drum, a clockwork spring and a rolling drum shaft; the upper end of the pulling belt extends into the airbag air pocket and is fixed with the part of the inner end face of the airbag air pocket in a seaming mode; the lower end of puling belt is glued on the rolling drum; one end of the rolling drum shaft is fixed to the central position of the rolling drum; the direction, deviating from rolling drum, of the rolling drum shaft is sleeved with the shaft sleeve, and the shaft sleeve makes contact with the rolling drum; the shaft sleeve is connected with the shell body through a shaft sleeve connecting piece; the rolling drum shaft is positioned through a gasket and a split pin in sequence after penetrating through the shell body; and the top end of the base is fixedly connected with the shaft sleeve, one end of the clockwork spring is inlaid in the shell body, and the other end of the clockwork spring is inlaid in the rolling drum shaft. When the air pocket expands, the air pocket pulls the pulling belt to drive the rolling drum and the rolling drum shaft to rotate, so that the clockwork spring stores the energy; and when the air pocket deflates, the clockwork spring drives the rolling drum and the rolling drum shaft to rotate toward the opposite direction, the pulling belt is recovered, and the air pocket is recovered, and the purpose of repeated using of the air pocket is achieved.

Description

technical field [0001] The invention belongs to the field of vehicle safety, and in particular relates to a recovery device for vehicle active safety airbag airbags. Background technique [0002] According to spot checks conducted by the traffic police and other departments, the rate of wearing seat belts on school buses is not satisfactory. Most students do not wear seat belts on school buses. Therefore, the protective effect of seat belts on child occupants is greatly reduced. When a school bus has a frontal collision, compared with child occupants wearing seat belts, due to inertia, child occupants not wearing seat belts will have a more violent secondary collision with the front seat and suffer greater injuries. Another point that needs to be paid attention to is that children themselves are lively and active, and their riding postures on the school bus are diverse, and the occupants will leave their seats; even if they wear seat belts, they may not meet the regulations ...
