The present invention discloses a kind of drawing expansion type safety belt, including inner layer (1) and fit in the surface layer (2) of the inner layer (1) periphery, the inner layer (1) is the tissue layer that feature is punched with surface linear type, and surface layer (2) are resin layer；The surface layer (2) is crosslinked shape polymer architecture by cross-linking reaction formation, is covered on inner layer (1) surface, and resin layer and tissue layer is made to be combined into the one that can laterally broaden when length direction stretches.Drawing expansion type safety belt of the invention, contact area is big after locking, local pressure is small, small to driver and passenger's secondary injury probability.
Description
Technical field
The present invention relates to vehicle occupant restraint system regions, after especially a kind of locking, contact area is big, local pressure is small,
The drawing expansion type safety belt small to driver and passenger's secondary injury probability.
Background technique
When automobile collides or when encountering undesirable emergency braking, huge inertia force will be generated, makes driver and multiplies
The rigid objects such as visitor and interior steering wheel, windshield, backrest, car door collide, and easily cause actual bodily harm.Make
For the chief component of occupant restraint system, safety belt can absorb a large amount of Impact energy, dissolve inertia force, play well
Buffer function.Meanwhile being firmly strapped in driver and passenger on seat, prevent body from contacting or being spilled over vehicle with interior rigid objects
Outside.
Chinese invention patent application specification " safety belt " (application number: 201310444669.5, publication date: 2014-01-
29) a kind of safety belt, including ribbon are disclosed, the ribbon includes: the internal ribbon ontology with accommodating space, and described
The gas band extended along the webbing length direction being arranged in the accommodating space of ribbon ontology, the gas, which takes, to be equipped with for institute
Gas band is stated to carry out inflatable and deflatable channel, the multiple airbags for being fixed on predeterminable area, the airbag being dispersed in the gas band
Inside is filled with gas, is connected to by the through-hole being arranged on the airbag with the gas band inside the airbag.
But above-mentioned belt-strap can generate after length direction bears tensile load locking because of the characteristic of own material
Lateral contraction, this causes the contact area that belt-strap acts on trunk after locking to reduce, it is possible to because of part
The increase of pressure leads to the damage of driver and passenger's thorax abdomen.
Summary of the invention
The purpose of the present invention is to provide a kind of drawing expansion type safety belt, after locking, contact area is big, local pressure is small, to driving
It is small to multiply personnel's secondary injury probability.
Realize the technical solution of the object of the invention are as follows:
A kind of drawing expansion type safety belt, including inner layer 1 and the surface layer 2 for fitting in 1 periphery of inner layer, the inner layer 1 is tool
There is the tissue layer of surface linear type punching feature, surface layer 2 is resin layer；The surface layer 2 is crosslinked shape by cross-linking reaction formation and gathers
Object structure is closed, 1 surface of inner layer is covered on, resin layer and tissue layer is made to be combined into can laterally broaden when length direction stretches one
Body.
Compared with prior art, remarkable advantage of the invention are as follows:
Contact area is big after locking, local pressure is small, small to driver and passenger's secondary injury probability.
The present invention is punched by carrying out vertical and horizontal periodically linear type on belt web layer, is guaranteeing that safety belt is strong
The deformation of " auxetic " formula is realized while degree, rigidity, wearability and extensibility, when increasing safety belt locking and trunk
Contact area, safety belt work causes the general of secondary injury to driver and passenger when reducing car crass or emergency braking generation
Rate.
Detailed description of the invention
Fig. 1 is the structure perspective diagram of one embodiment of drawing expansion type safety belt of the present invention.
Fig. 2 is periodic cells enlarged drawing in Fig. 1.
Fig. 3 is deformation schematic diagram of the periodic cells in locking in Fig. 1.
Specific embodiment
As shown in Figure 1, drawing expansion type safety belt of the present invention, including inner layer 1 and the surface layer 2 for fitting in 1 periphery of inner layer.
The inner layer 1 is the tissue layer that feature is punched with surface linear type, and surface layer 2 is resin layer；The surface layer 2 passes through
Cross-linking reaction forms crosslinking shape polymer architecture, is covered on 1 surface of inner layer, is combined into resin layer and tissue layer and draws in length direction
The one that can laterally broaden when stretching.
Preferably,
The surface linear type punching feature of the inner layer 1 refers to that fabric layer surface is distributed equipped with vertical and horizontal periodic regular, and
Mutually disjoint linear type slit.
Thin sight size, quantity and the deployment scenarios of the linear type slit, according to the intensity, rigidity and elongation percentage of safety belt
It is required that determining；Wherein required safety belt strength and stiffness are bigger, elongation percentage is smaller, then its thin sight size is smaller, and quantity is more, cloth
It sets closer.
Preferably,
The inner layer 1 is the width about 50mm being interwoven by synthetic fibres, the ribbon of thickness about 1.5mm.
Preferably,
The inner layer 1 material based on dacron polyester or polyamide polyester.
The surface layer 2 material based on polyacrylate or polyurethane.
During the cross-linking reaction, need to control the techniques such as suitable temperature, curing degree, the degree of association and functional group concentration
Parameter makes the wear-resisting property, mechanical strength and fast light, hot, cold performance of safety belt have improvement, and reach by appropriately crosslinked
To its related request；Wherein biggish curing degree will lead to difficult forming, and lesser curing degree then will increase molding cycle；Association
Degree is bigger with functional group concentration, and material is harder, on the contrary then inclined softer, elastic.
Fig. 2 is periodic cells enlarged drawing in Fig. 1.
Fig. 3 is deformation schematic diagram of the periodic cells in locking in Fig. 1.
It is 6mm that the width of linear type slit 101, which is 1mm, length, in figure, the linear type slit arranged along safety belt width direction
Spacing be 10mm, along safety belt width direction arrange linear type slit spacing be 5mm.Linear type slit can be in tissue layer
With different thin sight size, quantity and deployment scenarios, to obtain different intensity, rigidity and elongation percentage.Resin layer 2 is with poly-
Acrylate raw material are crosslinked shape polymer architecture by generating cross-linking reaction formation in tissue layer fiber, are covered on fabric
Layer surface makes resin layer and tissue layer be integrated.Cross-linking reaction process can pass through temperature, curing degree, the degree of cross linking and function
The technological parameters such as group's concentration are controlled, to meet wearability, low-friction coefficient and fast light, hot, the cold and intensity of safety belt
It is required that.
Drawing expansion type safety belt of the present invention, locking when automobile collides or when encountering undesirable emergency braking, safety belt with
The contact of driver and passenger's body, can be presented " auxetic " formula deformation behaviour as shown in Figure 3, i.e. elongated lengthwise under tension
While laterally broaden, to reduce pressure when increasing safety belt locking and the contact area of human body, reduce safety belt to driving
Personnel cause the probability of secondary injury.
