As further preferred embodiment, the lower section of the connecting portion 3 be equipped with fixed with the support bar top and Transverse part connected vertically, the connecting portion 3 is slidably connected on the transverse part so that the neck brace 2 can be relative to support Bar 1 is moved forward and backward.Front and rear adjusting can be then carried out as needed, and use is more humane, also more comfortable.

As further preferred embodiment, the supporting rod 1 is equipped with multiple card slots so that its coordinate with bayonet lock from And it is moved up and down relative to back bracket.

In the present embodiment, when specifically used, headrest support outer packing outer packing can become headrest bolster, connect on crossbeam 12 Head rest pole connecting portion 10 is connected to, which can be used as the bottom of motor vehicle seat back, the then backrest Portion carries out routine with automobile cushion and connect, and the top of backrest carries out routine with headrest bolster by head rest pole connecting portion 10 and connect, just As automotive seat.

Embodiment 2

On the basis of embodiment 1, as shown in Fig. 8~11, multiple elastic pieces 19, institute are equipped on the elastomeric element 13 The top for stating elastic piece 19 is connect with elastomeric element 13, and the bottom end of elastic piece 19 is free end, the elastic piece 19 and vertical side To angle be 0~30 degree, elastic piece 19 can increase elastic force while intensity is increased, reliable comfortable so as to increase Degree；And upper right is to lower extension, and equipped with certain angle, has multiple independent power for back, it is very comfortable in human body closing.

The top of the elastic piece 19 is fixedly connected with the elastic string 14, i.e., elastic piece 19 be equivalent at elastic string to Lower extension, elastic piece press to elastic string under pressure, and the two cooperation, human body experience sense is very strong, and comfort is very high.Elasticity Rope can be used as support, while can also provide elastic force enhancing comfort level, and three complements each other, and is easier to control backrest elastic force, Backrest is more comfortable.

The free end of the elastic piece 19 is set to the top of the support spring 15, i.e. support can be completely covered in elastic piece Spring 15, fitness higher, mutual elastic force concertedness are more preferable.

The distance between two neighboring elastic piece 19 be 2~5cm, generally 3~4cm, then spaced setting so that make The back of user is more comfortable.

The elastic piece 19 includes the inclined tab 20 being from top to bottom obliquely installed and the vertical side being connect with 20 bottom of inclined tab To the riser 21 of setting.The riser 21 is equipped with multiple protrusions 22 outwardly protruded, and the protrusion 22 includes raised line or salient point Deng, it can to a certain extent, elimination human body sense tired out makes one more comfortable.

When the elastic piece 19 presses to the elastomeric element direction by external force, the free end is overlapped on the bullet Property rope 14 on, elastic force between elastic string, elastic piece, support spring is made to be easier to coordinate and control.

The length of the inclined tab is 3~5cm, such as 4cm；The length of the riser is 4~8cm, such as 5cm, 6cm, 7cm.

As further preferred embodiment, the angle of the elastic piece 19 and vertical direction is 5~20 degree.

In the present embodiment, riser may be alternatively provided as the S types or broken line type of inside and outside direction bending, can also realize the work(of protrusion Effect.Elastic piece in the present embodiment extends from the top down, and free end is inclined outwardly certain angle so that user back is non- Normal comfortable, the specific installation position of elastic piece and elastomeric element so that it can cooperate, elastic strength bigger, it is easier to Elastic force is controlled, makes backrest more comfortable.Protrusion on elastic piece is set or is set as broken line type or S types, then enables elastic piece The effect of massaging is realized to back, in addition outer packing, the automobile back is extremely comfortable, and healthier, it is not easy to generate tired sense.

Embodiment 3

On the basis of embodiment 1 or 2, as shown in Figure 12~15, the top of the neck brace 2 passes through with the connecting portion 3 Torsional spring 51 connects, and the setting of torsional spring can be such that neck brace is moved forward and backward and certain buffering and comfort level, so that the neck brace 2 move backward under stress and pressure elimination after resiliently to reset condition.

One end that the connecting portion 3 is connect with the neck brace 2 is the hollow pipe 4 containing hollow cavity, and the torsional spring 51 is fixed With in the hollow cavity of the hollow pipe 4, the top of the neckpillow is fixedly connected with the end of the torsional spring 51.

Opening 40 is equipped on the connecting portion 3 with 2 junction of neck brace, the neck brace 2 can only be in the opening 40 It is moved forward and backward in width range；

The neck brace 2 in a free state, comes close to or in contact with (i.e. outer side edges on a 40 outer sides of the opening 41), in the case where there is pressure state, the neck brace 2 is moved to the opening 40 on a side (i.e. inner side edge 42) of inside.

Maximum move angle of the neck brace 2 in the opening 40 is 10~30 degree, i.e. α is 10~30 degree, too greatly then The hardness of headrest is inadequate, and too small then comfort level is inadequate, and too big too small uncomfortable, user experience is inadequate.

Angle Y between the face at the common place of outer side edges 41 and 3 axis of connecting portion of the opening 40 and vertical direction is 5 ~20 degree, such as 10 degree or 15 degree；I.e. neck brace 2 is inclined slightly outwards relative to connecting portion 3, and head can be as snug as a bug in a rug by getting on.

Angle beta between the face at the common place of inner side edge 42 and 3 axis of connecting portion of the opening 40 and vertical direction is 0 ~15 degree, such as 5 degree or 10 degree；When the weight on head is all placed on neck brace 2, understand there are one the process of slowly inside bullet, And intilted angle will not be very big, then it can be very comfortable by rest etc. up.

The torsional spring 51 is set to 52 periphery of axis, and the torque direction of 51 both sides of torsional spring is consistent, i.e., simultaneously by torsional spring Two ends are rotated to a direction, and the direction of the power such as screen resilience of torsional spring is consistent.

The 2 top both sides of neck brace are linked in the both ends of axis respectively, and on the axis 52,2 both ends of neck brace it is interior The outer ledge at side and 51 both ends of torsional spring is close to or close.

The 2 top both sides of neck brace are fixedly connected respectively with two ends of torsional spring 51.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, for this field For technical staff, the utility model can have various modifications and changes.All institutes within the spirit and principle of the utility model Any modification, equivalent substitution, improvement and etc. of work, should be included within the scope of protection of this utility model.
