Three-point sheet shaped safety belt for pregnant woman
Technical field
The present invention is mainly concerned with the automotive safety apparatus field, refers in particular to a kind of three-point sheet shaped safety belt for pregnant woman.
Background technology
To being in the women of childbearing age, traffic accident is the one of the main reasons that causes injures and deaths.In the collision of motor-driven vehicles accident, normally used safety strap can limit pregnant woman's thoracic cavity and pelvic movement, but pregnant woman's belly still is free to activity, the effect of inertia of sheep placenta water and fetus is on the uterus, causing UPI (placenta uterina contact surface) to locate the uterine wall strain value increases, when strain value surpasses 60%, then can cause placental abruption, make fetus can't obtain enough oxygen, finally cause foetal death.Therefore, the damage for pregnant woman occupant and fetus in the collision before reducing must reduce the strain value on the uterine wall.
Summary of the invention
The problem to be solved in the present invention just is: at the technical matters that prior art exists, the invention provides a kind of three-point sheet shaped safety belt for pregnant woman of simple and compact for structure, with low cost, easy to install, good reliability.
For solving the problems of the technologies described above, the solution that the present invention proposes is: a kind of three-point sheet shaped safety belt for pregnant woman, it comprises body-restraining seat belt, it is characterized in that: the sheet fabric that is equiped with the pregnant woman's belly that is used for fitting on the described body-restraining seat belt.
Described sheet fabric has an arc wrap that can fit with the belly of pregnant woman's projection.
Described body-restraining seat belt comprises shoulder belt, waistband and bracelet etc., and described sheet fabric is tied up by the frenulum more than two and is located on shoulder belt and the waistband.
The two ends of described frenulum are provided with the nylon adherent buckle that is used for connecting and adjusting frenulum length.
Compared with prior art, advantage of the present invention just is:
1, the strain value on the pregnant woman uterus wall before three-point sheet shaped safety belt for pregnant woman of the present invention can effectively reduce in the collision case improves parent and the fetal well-being of pregnant woman occupant in the automobile front collision accident.
2, three-point sheet shaped safety belt for pregnant woman of the present invention, simple in structure, easy to assembly, with low cost, can directly repacking on existing car belt.

The specific embodiment
Below with reference to the drawings and specific embodiments the present invention is described in further details.
As Fig. 1, Fig. 2 and shown in Figure 3, three-point sheet shaped safety belt for pregnant woman of the present invention, it comprises traditional body-restraining seat belt, be equiped with the sheet fabric 2 of the pregnant woman's belly that is used for fitting on the body-restraining seat belt, sheet fabric 2 has an arc parcel portion 10 that can fit with the belly of pregnant woman's projection, arc parcel portion 10 has certain space radian, thereby can wrap up pregnant woman's belly.Body-restraining seat belt comprises shoulder belt 1, waistband 3 and bracelet 7 etc., and this body-restraining seat belt encircles 9 three location and installation in automobile by bracelet 7, anchor point 8 and D.Sheet fabric 2 is tied up by the frenulum more than two 4 and is located on shoulder belt 1 and the waistband 3, and the two ends of frenulum 4 are provided with the nylon adherent buckle 5 that is used for connecting and adjusting frenulum length.In the present embodiment, make and walk around shoulder belt 1 respectively at the belt 4 on the upper and lower edge of sheet parcel fabric and be connected with waistband 3 and by nylon adherent buckle 5, because pregnant woman's abdominal configuration size changed along with the conceived time, the user can be according to the different adjustment bonding location of s own situation, make sheet parcel fabric can be fit to self belly size, better wrap up pregnant woman's belly.
Fig. 4 and Fig. 5 have provided the running condition figure of safety belt for pregnant woman, pregnant woman occupant wears original traditional body-restraining seat belt on the car earlier, should make shoulder belt 1 between two breast of pregnant woman, waistband 3 is as far as possible near the below of buttocks, and sheet fabric 2 is worn in adjustment according to s own situation again.Safety strap is not oppressed fetus during for the assurance automobile normal running, and sheet parcel fabric and pregnant woman's belly should have suitable gap.When before automobile takes place, colliding, the occupant is because the effect of inertia preshoot, sheet parcel fabric can be fitted with pregnant woman's belly, the parcel belly makes its buffering, but actv. reduces the strain value on the uterine wall that the inertia of sheep placenta water and fetus causes, prevent the generation of placental abruption, and traditional body-restraining seat belt can retrain parent well, when can avoiding harness tension excessive, force-limiting device wherein, ensured the safety of pregnant woman and fetus when before vehicle takes place, colliding to the compressing of fetus.In sum, the present invention be during according to automobile front collision to the protection requirement of pregnant woman and fetus, constraint parent motion and cushion its belly reduces the strain value on the uterine wall that the inertia of sheep placenta water and fetus causes, prevents placental abruption.
The above only is a preferred implementation of the present invention, and protection scope of the present invention also not only is confined to the foregoing description, and all technical schemes that belongs under the thinking of the present invention all belong to protection scope of the present invention.Should be pointed out that for those skilled in the art in the some improvements and modifications that do not break away under the principle of the invention prerequisite, these improvements and modifications also should be considered as protection scope of the present invention.
