Specific embodiment

The technical scheme in the utility model embodiment is clearly and completely described below, it is clear that described reality It is the utility model part of the embodiment to apply example, instead of all the embodiments.The embodiment of the utility model presented below Detailed description be not intended to limit claimed the scope of the utility model, but be merely representative of the selected of the utility model Embodiment.Based on the embodiment in the utility model, this field commonsense method personnel are without creative efforts All other embodiments obtained shall fall within the protection scope of the present invention.

Embodiment 1

As shown in Figure 1, a kind of rear portion shaped support applied in automotive seat head cushion, including for connecting seat The supporting rod 1 of chair back and the neck brace 2 being connect with the supporting rod 1, the supporting rod 1 are equipped with multiple card slots, so that its Coordinate to move up and down relative to backrest with bayonet lock.The neck brace 2 is equipped with the square of top end opening for u-bracket or top Shape stent, the top of the neck brace 2 are connect with the top of the supporting rod 1 by connecting portion 3.

As shown in Fig. 9~11, at least first spring 8 is transversely provided in the neck brace 2.Preferably laterally it is equipped with more the One spring 8, and 3~7cm is spaced between adjacent two first springs 8, such as 5cm left and right settings one.First spring 8 and neck brace 2 Cooperation is so that head has certain support, and the experience sense on head is more preferably more comfortable.

As further preferred embodiment, the flexible set 9 of 8 outer fitting of the first spring can protect head.By It is not fixed in the both ends of flexible boot 9 with neck brace, therefore it does not interfere with the first spring 8 and plays its normal elastic force and screen resilience.

As further preferred embodiment, the flexible boot is externally provided with multiple raised 91, contributes to head massage, relaxes Appropriateness is strong, healthy and beneficial to user.

Described raised 91 include at least one of the salient point outwardly protruded, lateral raised line and longitudinal raised line.It is preferred that transverse and longitudinal Raised line has, and crisscross setting, and dot bulge has been interspersed between raised line, i.e., described salient point is set to by lateral raised line In the concave lattice formed with longitudinal raised line.

As further preferred embodiment, pass through between the middle part of the neck brace 2 and/or lower end and supporting rod Two springs 10 connect, then can play a supporting role to a certain degree, increase tolerance and the service life of neck brace 2, and do not influence to make Neck brace 2 is moved forward and backward, and practicability is extremely strong.

The second spring 10 is parallel with the connecting portion.

As further preferred embodiment, the neck brace 2 is flexible stent or the neck brace 2 and support Bar 1 is elastic connection so that neck brace 2 can be mobile to 1 direction of supporting rod under stress and be recoiled to after contact Reset condition.

Embodiment 2

On the basis of embodiment 1, as shown in Figure 2-5, the top of the neck brace 2 passes through torsional spring 51 with the connecting portion 3 Connection, 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 is being pressed Moved backward under power 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.

Embodiment 3

On the basis of embodiment 1, as can be seen from figures 6 to 8, the lower section of the connecting portion 3 is equipped with and 1 top of supporting rod Transverse part 6 fixed and connected vertically, the connecting portion 3 is slidably connected on the transverse part 6 so that the neck brace 2 being capable of phase Supporting rod 1 is moved forward and backward.

The center of the transverse part 6 is equipped with multiple cavitys through 6 upper and lower end face of transverse part along 6 length direction of transverse part 61。

The clamping block 7 that can be moved up and down is vertically connected on the connecting portion 3, the clamping block 7 can be contained in institute It states in cavity 61.

The clamping block 7 includes lift lever 72 and the clamping joint 71 being connect with 72 bottom end of lift lever, the clamping The first 71 fusiformis structures outwardly protruded for middle part, and there is the clamping joint certain elastic deformation ability to allow it to across institute It states cavity 61 and the middle part outwardly protruded is connected to transverse part below 6.

The connecting portion 3 is equipped with the through-hole through connecting portion two end faces about 3, and the lift lever is through described logical Hole, the top of the lift lever is connected with Handheld Division so that user's operation is more convenient, and the Handheld Division is set to connecting portion 3 Top.

When no External force interference, the clamping joint is located in the cavity 61, and the middle part portion of clamping joint outwardly protrudes Place is located at 6 lower section of transverse part；When clamping block 7 is lifted up by external force, the connector lifts to the top of transverse part 6, At this point, the connecting portion 3 can be free to slide on transverse part 6；When external force moves down clamping block 7, clamping joint is again Into cavity 61, the connecting portion 3 is fixed with transverse part 6, i.e., connecting portion 3 can not slide on transverse part 6, realizes clamping.

The lower face of the connecting portion 3 is fixedly connected with lantern ring 31, and the lantern ring 31 is linked on the transverse part 6 and energy It is slided along transverse part 6.

In the utility model, the sliding type of connecting portion and transverse part may be the slip of other manner, as long as energy Realize the function.

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.
