Description

The head rest setting device of child's safety seat for vehicle

Technical field

The utility model relates to a kind of elevating adjusting device, especially a kind of head rest setting device of child's safety seat for vehicle.

Background technology

Automotive seat are typically equipped with head rest, though the head rest of configuration also can be realized lift adjustment, its setting range is generally less, because the growth of child development phase is very fast, according to European ECE44-R04 criteria classification, the height of the children head of I, II, III group, can be from the 620mm of 9kg to 36kg 760mm, variation range can reach 160mm, if directly the elevating adjusting device of automotive seat head rest is transplanted to child's safety seat for vehicle, obviously can not satisfy different group children's actual needs.

Summary of the invention

The purpose of this utility model is: at the elevating adjusting device of automotive seat head rest is transplanted to child's safety seat for vehicle, can not satisfy the practical problems of different group children's actual needs, a kind of head rest setting device of child's safety seat for vehicle is provided.

The purpose of this utility model is achieved in that a kind of head rest setting device of child's safety seat for vehicle, the head rest that comprises safety seat, it is characterized in that: the safety seat backrest is provided with the head rest stay bearing plate, be provided with lifting guide groove longitudinally in the head rest stay bearing plate, at least evenly be provided with two horizontal locating grooves along the lifting guide groove; Head rest is provided with the slot of head rest stay bearing plate, is provided with the locator card block in the slot, and the locator card block is provided with the button guide groove, and release-push comprises button and positioning wedged block, is furnished with spring between release-push and locator card block; In the slot that described head rest stay bearing plate insert head leans on, after the locator card block passes the lifting guide groove of head rest stay bearing plate, captive joint with head rest by screw in its end, the positioning wedged block on the release-push is butted on by spring in the locating groove of head rest stay bearing plate, and the slot wall that button passes head rest exposes.

In the utility model: the actual length of the lifting guide groove in the described head rest stay bearing plate should be greater than 160mm, and the lifting guide groove distance of the locating groove at two ends up and down is 160mm.

Advantage of the present utility model is: adopt by lifting guide groove, locating groove in the stay bearing plate to be connected with the safety seat backrest by the locator card block by the mode of spring and positioning wedged block, realize the head rest location, simple in structure, the location is reliable; Owing in the lifting guide groove a plurality of horizontal locating grooves are set evenly, behind release-push compressing positioning wedged block, slip-on head is by changing the residing position of locating groove of positioning wedged block engaging, and is easy to adjust; Because the lifting guide groove distance of the locating groove at two ends up and down is 160mm, its setting range is big.

Description of drawings

Fig. 1 is the head rest supporting plate structure scheme drawing that the utility model relates to;

Fig. 2 is the structural representation of the lift adjustment mechanism that relates to of the utility model;

Fig. 3 is a structural representation of the present utility model.

Among the figure: 1, head rest, 2, the head rest stay bearing plate, 3, the lifting guide groove, 4, locating groove, 5, slot, 6, the locator card block, 7, spring, 8, positioning wedged block, 9, release-push, 10, the safe chair backrest, 11, screw.

The specific embodiment

Accompanying drawing discloses the concrete structure of the utility model embodiment without limitation, and the utility model is further described below in conjunction with accompanying drawing.

As seen from Figure 1: be provided with lifting guide groove 3 longitudinally in the head rest stay bearing plate 2, at least evenly be provided with two horizontal locating grooves 4 along lifting guide groove 3; Head rest stay bearing plate 2 is fixed on the safe chair backrest 10.In the present embodiment, be provided with ten horizontal locating grooves 4 along lifting guide groove 3, the actual length of the lifting guide groove 3 in the head rest stay bearing plate 2 should 180mm, and the distance of the locating groove 4 at lifting guide groove two ends about in the of 3 is 160mm.

As seen from Figure 2: locator card block 6 is provided with the button guide groove, and release-push 9 comprises button and positioning

wedged block

8, and 6 of release-push 9 and locator card blocks are furnished with spring 7; Locator card block 6 passes the lifting guide groove 3 of head rest stay bearing plate 2, and the positioning wedged block 8 on the release-push 9 is butted on by spring 7 in the locating groove 4 of head rest stay bearing plate 2, and the slot wall that button passes head rest exposes.

As seen from Figure 3: head rest 1 is provided with the slot 5 of head rest stay bearing plate 2, head rest stay bearing plate 2 insert heads are by in 1 the slot 5, after locator card block 6 passes the lifting guide groove of head rest stay bearing plate 2, captive joint with head rest 1 by screw 11 in its end, positioning wedged block 8 on the release-push 9 is butted on by spring 7 in the locating groove of head rest stay bearing plate 2, and the slot wall that button passes head rest exposes.

When adjusting the height of head rest 1, as long as giving the button that exposes exerts pressure, when the pressure of release-push 9 elastic force greater than spring 7, release-push 9 will move along the button guide groove on the locator card block 6, when the positioning wedged block on the release-push 98 breaks away from the locating groove 4 of head rest stay bearing plate 2, change the position of head rest stay bearing plate 2 in the slot 5 of head rest 1, and then unclamp release-push 9, under the effect of spring 7, positioning wedged block 8 is butted in the locating groove 4 again.
