Description
Technical field
The present invention relates to annex in a kind of Automobile, especially relate to a kind of for using the fixed interface of safety chair seats of car for children.
Background technology
At present, based on seat demand attractive in appearance, the ISO-FIX interface of the safety chair seats of car for children of domestic and international vehicle is concealed, hides the binding site of position at seat cushion and backrest.At present, the ISO-FIX interface of safety chair seats of car for children, mainly comprises interface agent and interface trim, general and the interface agent of interface trim is hinged and connected, when use, interface is decorated and is stamped a large top that is exposed at seat cushions of cutting, and trim easily damages, and reliability of service is poor.
Be that the Chinese patent document that CN203126573U, name are called " a kind of child seat attachment point decorative cover " discloses a kind of child seat attachment point decorative cover in 2013-08-14 bulletin, notification number, " comprise casing for accommodating described child seat attachment point and for hiding the lid of opening of described casing; described lid comprises roller shutter and spool; described spool is fixed on a minor face of described opening, the long limit fore and aft motion that described roller shutter is wrapped on described spool and can be parallel to each other along two of described opening." exist problem be: complex structure, use inconvenience, spool structure is easily damaged, therefore reliability of service is poor.
Summary of the invention
Main goal of the invention of the present invention is to provide a kind of fixed interface of simple in structure, easy to use, safety chair seats of car for children that reliability of service is high.
The present invention's technical scheme used is: a kind of fixed interface of safety chair seats of car for children, comprises interface body and access flap; The upper end of interface body is that flange form frame, lower end are rectangular cylinder, the rear side of two sidewalls in left and right of the lower end of interface body is provided with the guide groove moving towards up and down symmetrically, the upper end of front side is provided with knock hole symmetrically, and the rear side of the medial surface of two sidewalls in left and right of the lower end of interface body is provided with spacing projection in the front that is positioned at described guide groove upper end; That the rear and front end of described access flap is provided with is curved under arc, roll under two ends left and right, and wherein the lower edge of the rear end of lower folding is triangle lower than the front end of the lower edge at the middle part of lower folding, lower folding; The rear end of the lower folding at two ends, access flap left and right is provided with the guidepost that inserts from inside to outside guide groove, and the front end of the lower folding at two ends, access flap left and right is provided with the positioning convex with knock hole cooperating; Access flap covers in the time of the oral area of interface body, and the front and rear edge of the front and back end of access flap and the nozzle of interface body has gap.
