Abstract
The object of the invention is a headrest comprising at least one mounting prong (11) for a seat back, particularly an automobile seat, and an attached cushion (10). According to the invention, the cushion comprises a first part (10a) in which the prong is inserted and which is stationary in relation to the prong, and a second part (10b) which is attached to the first part.
Description
The present invention relates to a kind of headrest assemblies, particularly modules of said type, it comprise at least one be installed on the spinal support, the bar on the car seat particularly, and be hinged on back cushion on the described bar.
This assembly is well-known, generally has two bars, and back cushion is fixed on its top.Fig. 1 and 2 is in the mode of cutaway view, represented headrest assemblies well known in the prior art, such from front and side respectively.
These known headrests have following shortcoming, housing and the aperture that allow to pivot because it needs protection, and because these parts also need extra fixing operation in the headrest manufacturing process, so it is complicated and costliness.
The objective of the invention is to overcome these shortcomings.
Therefore, theme of the present invention is, a kind of headrest assemblies comprises at least one bar that is installed on spinal support, particularly the car seat backrest, an and pivotally attached back cushion, wherein, back cushion comprises that described bar penetrates wherein and can not be relative to the first that this bar moves, and first's pivotally attached second portion relatively.
Like this and since bar penetrate on the back cushion, can not be relatively their parts of moving, so do not need to allow the device that moves, particularly can save aperture.In addition, if do not need to seal hinge axis, and if any acute angle spare that does not for security reasons need protection, so also can save housing.
In a specific embodiment, the described second portion of back cushion carries out hinged on its top.
Therefore, to carry out the pivotally attached conventional confguration with back cushion in its bottom be opposite to this structure.In this embodiment, the first of back cushion extends downwards from the top of the movably second portion of back cushion.
Can see that known headrest is because the following fact also has another shortcoming, promptly under case of collision, hinge axis must bear the head applied pressure by the user.Therefore, hinge axis must be sturdy and durable especially.On the other hand, in the foregoing description, because the movable part of back cushion will be tight against mounting rod, and mounting rod itself is fixed on the seat firmly, so under situation about being collided, hinge axis can not have problems.
Why Here it is will install energy absorbing device between the second portion of the described bar of this embodiment and described back cushion reason.
More particularly, described back cushion can comprise that one is embedded in the skeleton in a large amount of foams, for example, and the plate that top one that install along the one lateral edges, can described relatively bar pivots.
Also can comprise setting device according to assembly of the present invention, for example a ratchet, a button or a knob.
Also specific embodiments more of the present invention are described with reference to the accompanying drawings by nonrestrictive example now, wherein:
Fig. 1 and 2 has described the headrest of prior art;
Fig. 3 is the cutaway view of describing according to headrest assemblies principle of the present invention;
Fig. 4 is the cutaway view that is similar to the specific embodiment of Fig. 3.
Introduced Fig. 1 and 2 before this, no longer repeated here.
Fig. 3 has represented one according to headrest assemblies of the present invention, and it comprises by two parts 10a and 10b back cushion 10 that form, mutually hinged.This back cushion is installed in any known way and is fixed on the mounting rod 11 on the backrest at a seat.
The bottom of the part 10a of these bar 11 process back cushions is interior side-prominent from back cushion 10.This part 10a can not move relative to bar 11, and this means does not need mobile device that bar is drawn from back cushion.
In this embodiment, hinge axis 13 is formed at the top of the part 10b of back cushion 10, forms an acute angle thus between part 10a and 10b, and therefore, in general, back cushion 10 has inverted V-arrangement.
If referring now to Fig. 4, can see a headrest with the same type of Fig. 3.
In this embodiment, the skeleton of the second portion 10b of back cushion is made up of plate 14, and it is crooked, forms all planes of part 10b.Plate 14 is reinforced by rib 15.Plate 14 and rib 15 can be made or be formed by plastics are integrally moulded by steel.
Plate 14 is installed on the main shaft 16 along the upper limb of main shaft, and main shaft 16 is installed on the top of bar 11.
Ratchet system can be used to adjust the degree of dip of the part 10b of back cushion 10 with respect to part 10a.In this embodiment, this system comprises that one is fixedly mounted on the tooth parts 16 on the rib 15, and a part 17 that has on fixed part 10a complementary teeth, that be hinged on back cushion, and part 17 is being tight against part 16 under the effect of unillustrated springing.
The energy absorbing device 18 of one known type also is provided in present embodiment, and this device is fixed on the bar 11 and is relative with the part 10b of back cushion.These energy absorbing devices 18 are embedded in the part 10a of back cushion.When the part 10b that is applied to back cushion along the direction of arrow F1 as a fierce power goes up, this part pressurized and replacing part 10a, and collision energy is absorbed by device 18.Thereby user's head is protected in fierce collision.
Available any suitable method is made back cushion 10.For example, can comprise the isocyanurate foam 19 of expansion that is embedded in above-mentioned all devices, but its moulded-in-place 20 li of drop cloth, and drop cloth 20 is formed with single die cavity, and with any suitable material, make such as fabric or plastics.
Back cushion can be made like this, at first makes drop cloth, stays three holes in the junction of drop cloth, two passages wherein as bar 11, and the 3rd hole used for injected foam.In the drop cloth that launches to shakeout, put the assembly that comprises bar, skeleton and hinge axis then well.Folding then this assembly and drop cloth.
Under the part 10a of back cushion and 10b mediate the situation of angle position, carry out molded.
Under any circumstance, packing material 19 must have enough flexibilities, with the part 10a that is implemented in back cushion and the required pivot between the 10b.
