Abstract
The utility model discloses a head rest elevating system, including a back frame, a head rest frame and an operating parts, wherein the back has set up a guide rail to length direction distribution along the guide rail is equipped with a plurality of location portions, the head rest has erect a stalk portion along guide rail removal, but this stalk portion is equipped with each location portion of bales catch income of block portion, the head rest frame is exposed to the one end of operating parts, and the other end connects with system of block portion. The utility model discloses a head rest elevating system goes into each location portion through block portion bales catch, makes the head rest frame can fix one by selected position, carries the operating parts through drawing, can make block portion recess each location portion, and the discount leans on to put up can readjust its position. The utility model discloses simplified head rest elevating system's structure, it is easy to exempt from with spring, equipment, greatly reduced manufacturing cost and assembly costs.
Description
Technical field
The utility model relates to a kind of head rest elevating mechanism, is specifically related to a kind of head rest elevating mechanism of exempting from spring.
Background technology
Head rest elevating mechanism is installed in the chair back of automobile seat heightening pad or general seat conventionally, and discount leans on can be according to taking advantage ofSeat person's needs are positioned at the suitableeest position.
The head rest elevating mechanism of knowing at present, its inner spring that uses, structure is too complicated, the not only many but also assembling of partTime-consuming, production cost is higher. Therefore, be necessary that research is a kind of simple in structure, assembling is easy to head rest elevating mechanism.
Utility model content
For addressing the above problem, the purpose of this utility model is to provide a kind of inside there is no spring and holds easy-to-assemble headBy elevating mechanism.
The utility model is realized in the following way:
A kind of head rest elevating mechanism, comprising:
One back rest, is provided with a guide rail, and is distributed with a plurality of location divisions along the length direction of guide rail;
One headrest frame, is provided with a shank and moves along guide rail, described shank be provided with a holding section at least can automatically buckle into each fixedPosition portion one of them, make headrest frame be fixed on a chosen position; And
One operating parts, headrest frame is exposed in one end, and the other end and holding section system connect.
Described back rest is the chair back of a seat or the chair back of an automobile seat heightening pad.
Preferably, described holding section and shank are integrally formed.
Preferably, described holding section comprises one section of elastic arm and a projection, and this projection is positioned at the free end of this section of elastic arm, and profitKeep snapping in respectively this location division by the elasticity strength of this section of elastic arm.
Preferably, described operating parts is the plastic sheet of a ribbon, strip, sheet metal or the hawser of strip, and one end is from head restExpose the upper end of frame, and the other end and elastic arm system connect.
Preferably, described headrest frame is provided with a hand hole or handle, forms a position that can grip.
Head rest elevating mechanism of the present utility model, buckles into each location division automatically by holding section, and headrest frame is fixedIn a chosen position, carry operating parts by drawing, can make holding section recess each location division, allow headrest frame be readjusted itPosition.

Detailed description of the invention
As shown in Figures 1 to 4, be a head rest elevating mechanism of implementing according to the utility model, can be installed in an automotive seatsThe chair back of chair elevating pad 4, or be installed in the chair back of general seat, discount is put by can be positioned on a chosen right position.
Head rest elevating mechanism of the present utility model, can comprise a back rest 1, a headrest frame 2 and an operating parts 3; Wherein lean onBackrest 1 is provided with a guide rail 11, and is distributed with a plurality of location divisions 12 along the length direction of guide rail 11.
The upper end of headrest frame 2 can be in order to fix a head rest, and lower end is provided with a shank 21 in order to the guide rail 11 along on back rest 1Move up and down. Shank 21 be provided with a holding section 22 at least can automatically buckle into respectively this location division 12 one of them, make headrest frame 2To be fixed on a chosen position.
Holding section 22 comprises one section of elastic arm 221 and a projection 222, and projection 222 is positioned at the free end of elastic arm 221, and utilizesThe elasticity strength of elastic arm 221 keeps snapping in each location division 12.
For reducing assembly cost, preferably, the holding section 22 that can utilize the integrally formed the present embodiment of plastic injection mould withShank 21, makes single component.
Operating parts 3 can utilize the plastic sheet of general ribbon, strip, sheet metal or the hawser of strip implement or form oneEnd exposes headrest frame 2, and the other end and holding section 22 are to connect. As shown in Fig. 3 and 4, while adjusting headrest height, can propose operation by drawingThe location division 12 that part 3 is recessed holding section 22 originally to snap in, makes headrest frame 2 be readjusted its position.
Preferably can establish a hand hole 23 or handle 24 on headrest frame 2, forms a position that can grip to facilitate adjustment headThe height and position leaning on.
The utility model has been simplified the structure of head rest elevating mechanism, exempts from spring, assembles easily, can reduce production costsAnd assembly cost.
