Abstract
The invention discloses a pre-tightening automotive safety belt. The pre-tightening automotive safety belt comprises a belt and a retractor, wherein the retractor is fixed on an automobile body through a bracket (17) which is connected with a winding drum (11) through a locking device and an unlocking device, the winding drum (11) for winding the belt is connected with a spiral spring (19), the bracket (17) is also provided with a steel ball type mechanical pre-tightening device connected with the winding drum (11), clamping teeth in a base (1) of the locking device are clamped by an induction rod (2) on the locking device under the effect of inertia and drive an irregular part by rotating a spine disk (5) of the locking device, the unlocking device is internally provided with an unlocking device pawl (5) for controlling the unlocking of the winding drum (11) and a steel ball (7), and the mechanical pre-tightening device consists of a bending pipe (14) internally provided with a generator, a winding drum ball wheel (13) and a steel ball bag (16). The pre-tightening automotive safety belt has the beneficial effects of being safe and reliable and being long in service life by adopting the steel ball type mechanical pre-tightening device.
Description
Technical field
The present invention relates to car belt, be specifically related to a kind of pretension car belt.
Background technology
Belt with pre-load device is a kind of fender guard of the driver and crew's of protection safety, and it has when auto against acquires a certain degree, and starts preloader; make the taking-up device automatic rewinding; eliminate the gap between occupant and the seat, make the occupant back can be close to seat, protect personal safety effectively.At present, belt with pre-load device on the market, form by taking-up device, support, piston tube, gas generator etc., what wherein use in the piston tube is the pill of aluminium, because pill of aluminium light weight, poor rigidity, impulsive force is less under gas promotes, and very easily is out of shape in collision, influence normal operation, caused potential safety hazard.
Summary of the invention
At the shortcoming of existing car belt, the invention provides a kind of later-model pretension car belt.
To achieve these goals, invent the measure of being taked:
A kind of pretension car belt, comprise ribbon and taking-up device, taking-up device is fixed on the vehicle body by support, and support is connected with reel by mechanical brake and unlocking device, the reel that twines ribbon is connected with clockwork spring, also is provided with on the support and reel bonded assembly ball type machinery pre-tightening apparatus.
Be arranged on induction rod on the mechanical brake and block latch in the mechanical brake base under effect of inertia, latch is by rotating the moving profiled piece of mechanical brake sour jujube dribbling.
Be provided with the unlocking device ratchet and the steel ball of the release of control reel in the unlocking device.
The machinery pre-tightening apparatus is made up of bend pipe, reel pearl wheel and the steel ball bag of built-in producer.
Described bend pipe is a L type.
Beneficial effect of the present invention: adopt ball type machinery pre-tightening apparatus, safe and reliable, long service life.

The specific embodiment
See also its implementation process of description of drawings:
A kind of pretension car belt, comprise ribbon and taking-up device, taking-up device is fixed on the vehicle body by support 17, support 17 is connected with reel 11 by mechanical brake and unlocking device, the reel 11 that twines ribbon is connected with clockwork spring 19, the number of turns decision that the size that furls power is furled by the thickness of clockwork spring 19 and width and ribbon, also be provided with on the support 17 and reel 11 bonded assembly ball types machinery pre-tightening apparatus; Be arranged on induction rod 2 on the mechanical brake and block latch in the mechanical brake base 1 under effect of inertia, latch drives profiled pieces by rotating mechanical brake sour jujube dish 5; Be provided with the unlocking device ratchet 5 and the steel ball 7 of 11 releases of control reel in the unlocking device; The machinery pre-tightening apparatus is made up of bend pipe 14, reel pearl wheel 13 and the steel ball bag 16 of built-in producer, place the gas generator in the bend pipe 14 to receive that energizing signal point is quick-fried, moment produces a large amount of gases, promoting a series of balls moves in bend pipe 14, and then make the reel pearl take turns 13 retrograde rotations, ribbon furls, and described bend pipe 14 is a L type.Beneficial effect of the present invention: adopt ball type machinery pre-tightening apparatus, safe and reliable, long service life.
Those skilled in the art's simple change and replacement all are within the protection domain of invention in this area.
