When the width and thickness of the left waistband 7 and the right waistband 8 gradually change, in an embodiment of the present invention, the length of the cross section of the left waistband 7 or the right waistband 8 perpendicular to the length direction is 56mm, the height (the thickness of the left waistband 7 or the right waistband 8) is 10mm, and the length of the cross section of the connecting buckle end is 22mm, and the height is 3.2 mm. When the width and thickness of the left waistband 7 and the right waistband 8 are not changed, in an embodiment of the present invention, the length of the cross section of the left waistband 7 or the right waistband 8 is 22mm, and the height (the thickness of the left waistband 7 or the right waistband 8) is 3.2 mm.

Furthermore, in the utility model, on the section perpendicular to the length direction, the ratio range of the length to the width of the inner core 4 of the left waistband 7 is 10:1 to 6: 1; the ratio of the thickness of the coating body 3 of the left waistband 7 to the thickness of the inner core 4 of the left waistband 7 ranges from 2:1 to 2:3, and the ratio of the width ranges from 3:2 to 5: 3. The ratio of the length to the width of the inner core 4 of the right waistband 8 ranges from 10:1 to 6: 1; the ratio of the thickness of the coating body 3 of the right waistband 8 to the thickness of the inner core 4 of the right waistband 8 ranges from 2:1 to 2:3, and the ratio of the width ranges from 3:2 to 5: 3. Compared with the left shoulder belt 5 and the right shoulder belt 6, the left waist belt 7 and the right waist belt 8 have stronger deformation resistance after plastic forming, meet the use habit of users (namely, the activity range above the waist is large, and the activity range at the waist is small), and have more obvious constraint effect. Preferably, in a cross section perpendicular to the longitudinal direction, the cover 3 of the left lap belt 7 extends toward the seat at both ends, and the cover 3 of the right lap belt 8 extends toward the seat at both ends.

Further, the utility model discloses in, crotch area 9 is connected with the seat joint, and the one end card of being connected with the seat is in the seat, and the buckle is connected with the one end of buckle connection. Preferably, the shape selection of the crotch strap 9 can be adjusted only in the length direction with reference to the shape selection of the left shoulder strap 5 or the right shoulder strap 6, that is: the inner core 4 of the crotch strap 9 has a uniform contour in the length direction, and the ratio of the length to the width of the inner core 4 of the crotch strap 9 in a cross section perpendicular to the length direction ranges from 10:1 to 4: 1; the ratio of the thickness of the cover 3 of the crotch strap 9 to the thickness of the core 4 of the crotch strap 9 ranges from 2:1 to 3:1 and the ratio of the width ranges from 3:2 to 3: 1. In one embodiment of the present invention, the length of the cross section of the inner core 4 of the crotch strap 9 is 11.8mm, the height is 1.2mm, and the radius of the fillet is 0.6mm on the cross section perpendicular to the length direction; the crotch strap 9 has a cross-sectional length of 22mm and a height of 3.2 mm.

Further, the utility model discloses in, the surface of the cladding body 3 of crotch area 9 includes crotch lateral surface and crotch medial surface, and on perpendicular to crotch area 9 length direction's cross-section, crotch lateral surface and crotch medial surface are the arcwall face, and crooked orientation is unanimous, and both ends extend towards the seat. The average curvature of the crotch outer side surface is larger than the average curvature of the crotch inner side surface. Compared with the left waistband 7 and the right waistband 8, the crotch strap 9 has a little resistance to deformation after plastic molding, and can form a new shape when touched by a user, thereby improving wearing comfort and reducing a binding feeling of the user.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of the invention or which are equivalent to the scope of the invention are embraced by the invention.
