Abstract
The invention relates to a collision energy release device for a car safety seat and belongs to the technical field of child safety seats. The collision energy release device comprises a safety belt pulling strip; the safety belt pulling strip is folded to form a first layer of safety belt, a second layer of safety belt and a third layer of safety belt; an N-shaped suture section is arranged on the safety belt pulling strip; and the first layer of safety belt and the second layer of safety belt in the N-shaped suture section are sutured in a shape like a Chinese character 'ji'. The collision energy release device for the car safety seat has the benefits that the structure is simple, and the design is reasonable; and when the collision occurs, a car suddenly stops, and a child continuously moves forwards at the same speed to drive the safety belt to begin to tear from a long suture position or totally tear along a suture position shaped like a Chinese character 'ji', so that the buffering time of the child is prolonged by 50-150 milliseconds, the collision energy is adsorbed, and the child injury is reduced.
Description
Technical field
The invention belongs to the child safety seat technical field, be specifically related to a kind of safety chair seats of car collision energy release gear.
Background technology
Child safety seat is exactly a kind of designed for children that aims at different weight (or age bracket), is installed in the automobile seat of energy Effective Raise children riding safety.Child safety seat is in the situation that auto against or suddenly deceleration are moved the injury that alleviates them thereby can reduce to children's stamping press and the health of limiting child.
Yet, the restraint strap that existing child safety seat band forms adopts, restraint strap just is strapped in children on the safety seat firmly when bumping, not buffer action.
Summary of the invention
Problem for prior art exists the object of the invention is to design the technical scheme that a kind of safety chair seats of car collision energy release gear is provided.
Described a kind of safety chair seats of car collision energy release gear, comprise the safety strap drawstring, the folding formation of described safety strap drawstring ground floor safety strap, second layer safety strap and the 3rd layer of safety strap, it is characterized in that described safety strap drawstring is provided with a N-type and sews up section, ground floor safety strap and second layer safety strap are sewed up by several fonts in the described N-type stitching section.
Described a kind of safety chair seats of car collision energy release gear is characterized in that the middle length of sewing up section of a few font sutures of described ground floor safety strap and second layer safety strap is 20～80mm, and the length that avris is sewed up section is 0～50mm.
Described a kind of safety chair seats of car collision energy release gear is characterized in that the middle length of sewing up section of a few font sutures of described ground floor safety strap and second layer safety strap is 40～60mm, and the length that avris is sewed up section is 15～35mm.
Above-mentioned a kind of safety chair seats of car collision energy release gear, simple in structure, reasonable in design, when bumping, the automobile cut, children continue to move forward with same speed, driving safety strap begins to tear or all tear from long suture along a few font sutures, thereby prolong 50～150 milliseconds of children surge time, absorb collision energy, reduce children injury.
Description of drawings
Fig. 1 is automobile children safety chair constructional drawing of the present invention;
Fig. 2 is safety strap pulling belt structure figure of the present invention;
Fig. 3 is use state reference map of the present invention;
Fig. 4 is the enlarged drawing (being that safety strap drawstring of the present invention is sewed up scheme circuit) at A place among Fig. 3.
Among the figure: the 1-safety strap; The 2-children; The 3-seat; The 4-base; 5-safety strap drawstring; 6-ground floor safety strap; 7-second layer safety strap; The 3rd layer of safety strap of 8-; Sew up section in the middle of the 9-; The 10-avris is sewed up section.
The specific embodiment
Further specify the present invention below in conjunction with Figure of description.
As shown in Figure 1, child safety seat comprises safety strap 1, safety strap drawstring 5, seat 3 and base 4.Children 2 are sitting on the seat 3 by safety strap 1 and 5 protections of safety strap drawstring.
Shown in Fig. 2-4, safety strap drawstring 5 folding formation ground floor safety strap 6, second layer safety strap 7 and the 3rd layer of safety strap 8.Safety strap drawstring 5 is provided with a N-type and sews up section, and ground floor safety strap 6 and second layer safety strap 7 are sewed up by several fonts in the N-type stitching section.After sewing up, ground floor safety strap 6 and second layer safety strap 7 consist of the N-type structure with the 3rd layer of safety strap 8.
The length of sewing up section 9 in the middle of ground floor safety strap 6 and second layer safety strap more than the 7 font sutures is 20～80mm, the length that the middle avris of sewing up section 9 both sides is sewed up section 10 is 0～50mm, the length of sewing up section 9 in the middle of being preferably is 40～60mm, the length that avris is sewed up section 10 is 15～35mm, the length of sewing up section 9 more preferably is 50mm, and the length that avris is sewed up section 10 is 25mm.
After safety strap drawstring 5 arranges several fonts stitchings of N-type stitching section and ground floor safety strap 6 and 7 employings of second layer safety strap, so that when bumping, the automobile cut, children continue to move forward with same speed, driving safety strap begins to tear or all tear from long suture along several fonts stitchings, thereby prolong 50～150 milliseconds of surge time of children (obtaining according to Collision test), absorb collision energy, reduce children injury.
Shown in the above and the figure only is preferred implementation of the present invention.Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the principle of the invention, can also make some modification and improvement, these also should be considered as belonging to protection scope of the present invention.
