Abstract

The utility model relates to a structure of a safety seat for children on an automobile, in particular to a hand regulating device of an automobile safety seat head rest for the children. The utility model comprises that a backrest is connected with the seat, and the upper end of the backrest is provided with the head rest. The upper end of the backrest is fixedly provided with an inserting plate which is plugged with an inserting slot on the head rest. A plurality of horizontal necks are uniformly arranged on the back of the inserting plate at a certain interval from top to bottom. The back wall of the inserting slot is provided with a window on the position corresponding to the necks, and a pressing plate is laterally crossed over the window. The inner side of the pressing plate is fixedly provided with a tappet which is fastened in one neck. The two ends of the pressing plate are arranged on the basal body of the head rest through screws which are sheathed with springs. Additionally, a manual pressing rod is fixedly connected with the pressing plate, the upper end of the manual pressing rod is backwards bent to a certain angle, and then a lever structure which makes the bent position as a fulcrum is formed. The utility model which can manually regulate the height of the automobile safety seat head rest for the children is of simple structure and of convenient and reliable regulation.

Description

Safety chair seats of car for children head rest hand adjustment device

Technical field

The utility model relates to a kind of safety seat structure of using for children on automobile, specifically be a kind of safety chair seats of car for children head rest hand adjustment device.

Background technology

Existing common safety chair seats of car for children, its backrest height is generally fixed, and so in use, its head of the children of all ages and classes, height often can not just lean against the head rest position at backrest top, thereby traveling comfort is relatively poor.

Summary of the invention

Technical problem to be solved in the utility model is, but provides a kind of manual regulation safety chair seats of car for children head rest height, while failure-free safety chair seats of car for children head rest hand adjustment device simple in structure, easy to adjust.

Safety chair seats of car for children head rest control apparatus of the present utility model includes one and seat bonded assembly backrest, there is a head rest backrest upper end, it is characterized in that, the backrest upper end is fixed with a plate, a slot socket connection on it and the head rest, the back side of described plate evenly is provided with the draw-in groove of many levels from top to bottom with a determining deviation, the position relative with draw-in groove at the rear wall of slot has window, a pressing plate is arranged laterally on window, the pressing plate inboard is fixed with a tappet, this tappet is stuck in the draw-in groove, the pressing plate two ends are installed on the matrix of head rest by the screw that is with spring, also have a manual depression bar to captive joint with pressing plate, manually the depression bar upper end is turned up certain angle backward, and constituting one is the lever construction of fulcrum with the bending place.

The utility model is simple in structure, only need press manual depression bar in the use, can move up and down head rest easily, unclamps manual depression bar tappet is rested in the draw-in groove of differing heights, and head rest is fixed, thereby reaches convenient purpose of regulating the head rest height.

The specific embodiment

As shown in the figure, in this safety chair seats of car for children head rest control apparatus, there is a head rest 2 backrest 1 upper end, between backrest and the head rest by the 4 mutual socket connections of the slot on 3 head rests of the plate on the backrest, the plate back side evenly has many horizontal draw-in grooves 5, simultaneously on the head rest on the rear wall of slot the position relative with draw-in groove have window 6, a tappet 8 that is fixed on the pressing plate 7 passes window and cooperates with draw-in groove, pressing plate 7 is installed on the matrix of head rest 2 by the screw 10 that is with spring 9, be fixedly connected with a manual depression bar 11 on the pressing plate 7, manually the depression bar upper end is turned up certain angle backward, and constituting one is the lever construction of fulcrum with its bending place.

When head rest was in positioning states, as shown in Figure 3, at the head rest dorsal part, because the pressure of screw upper spring 9, the tappet 8 on the pressing plate 7 was crushed in the clamp bar slot 5 of plate on the backrest, and this moment, head rest 2 rested on the certain altitude; When needs were regulated the head rest height, as shown in Figure 5, manually depression bar 11 upper ends were pressed, because leverage, pressing plate 7 and tappet 8 are lifted backward, break away from draw-in groove, can freely move up and down head rest 2 this moment, and it is adjusted on the height that needs, and unclamps manual depression bar again and promptly finish and reorientate.
