Abstract
The utility model relates to an elastic headrest, which comprises a headrest body and clamping teeth and a spring, wherein two fixing supports are connected under the body, the clamping teeth and the spring are arranged on the two fixing supports, each fixing support is divided into two sections by the spring, and the spring is fixed between the two sections. By the elastic deformation of the helical spring, the utility model can change the front and back angles of the headrest, increases the mobility and flexibility of the head, reduces the fatigue of the head and the neck, improves the comfortableness of the sitting, and at the same time, effectively protects the head and neck part of riders and drivers.
Description
Technical field
The utility model relates to automobile-used passenger and uses equipment technical field, specifically is involved in the structure of a kind of automobile with headrest.
Background technology
Automotive headrest is the vitals of automotive trim seat; when riding in an automobile for a long time; driver and crew usually can feel that the neck fatigue aches; this causes owing to the neck vertebra can not get effective support; headrest is when providing comfort for driver and crew; when taking place, traffic accident can protect driver and crew's neck safety better; automobile is subjected to impact force action moment rapidly forward; because effect of inertia driving staff's head but can be suddenly to layback; cervical vertebra is subjected to very big acceleration/accel and is injured; the headrest support has been arranged; reduce space that head moves freely and just can reduce impulsive force cervical vertebra, the evidence hindbrain with rest the head between the front and back safety distance empirical value should be less than 50 millimeters, the smaller the better; in the time of can reducing to have an accident like this and the bump of headrest, therefore the improvement of headrest be very necessary.Automotive headrest is to be fixed on the backrest of seat by 2 rigidity steel columns at present, headrest is except highly can regulating, front and rear angles mostly can not be regulated, make passengers inside the car's head lean against when resting the head on upward more stiff, so be easy to generate fatigue phenomenon for a long time, when rear-end collision took place, the generation neck was injured easily to cause occupant's head to move backward simultaneously.
Patent Office of the People's Republic of China discloses a kind of adjustable automotive headrest, and Granted publication number is CN201086656Y, and the document comprises two intubate, tranverse connecting rod, clip, adapter plate and degree of tightness parts; Clamp is on tranverse connecting rod, and adapter plate is captiveed joint with clip; Described two intubate are in parastate, and an end of two intubate is respectively equipped with attaching parts, and this attaching parts is connected with the degree of tightness parts and is connected with tranverse connecting rod, by the degree of tightness parts attaching parts and tranverse connecting rod are formed and loosen, tighten the formula movable connection structure.Two intubate of this structure are rigid material, and are more stiff in the time of can making passengers inside the car's head lean against headrest to go up, and so are easy to generate fatigue phenomenon for a long time, and when rear-end collision took place, the generation neck was injured easily to cause occupant's head to move backward simultaneously.
The utility model content
Automotive headrest is except highly can regulating at present, front and back mostly can not be swung, the utility model is easy to generate fatigue in order to solve to take advantage of for a long time in the prior art to drive, and the injured problem of neck takes place the occupant easily when rear-end collision takes place, and has proposed a kind of elasticity headrest features.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of elasticity headrest, comprise head rest body, two fixed mounts of bonded assembly under the body, the chucking tooth and the spring that are provided with on the fixed mount, each fixed mount is divided into two sections by spring, and spring is fixed between these two sections.Being provided with spring on fixed mount can make headrest along with occupant back extruding seat automatically upwards and regulate forward; improved the comfort level that the driving staff takes; also protected simultaneously driving staff's head and neck; spring is selected coil spring for use; spring makes head lean against like this and can not feel stiff top the time when bending generation elastic deformation, also can not seem soft because of deformation angle is excessive; when head is subjected to quickening backward power, head is played support simultaneously.
The length of spring is 3cm-10cm, and the spring wire diameter is 2mm-4mm.Spring is strong like this, and intensity ratio is bigger.
Fixed mount and spring bonded assembly termination are provided with chamfering.Make fixed mount inject spring easily like this.
Compared with prior art; the beneficial effects of the utility model are: by helical spring elastic deformation; can change the front and rear angles of headrest; make the mobility and flexibility of head increase; reduce the fatigue of head and neck; improve the traveling comfort of taking, also protected driving staff's head and neck simultaneously effectively.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail: as shown in Figure 1, selecting length for use is 20cm, diameter is 10mm, thickness is that two steel pipes of 1mm are made fixed mount 2, each fixed mount 2 is divided into two sections, one segment length 5cm, one segment length 15cm, a termination of two sections is respectively equipped with chamfering, and short one section does not have an end of chamfering to be connected with head rest body 1, and one section long steel pipe is provided with chucking tooth 4, selecting two steel wire diameter for use is 3mm, length 5cm, internal diameter are that the end that 3, two sections steel pipes of coil spring of 9mm are provided with chamfering injects 2cm in the spring, make fixed mount 2 close-fittings in spring 3, process cooresponding hole at fixed mount 2 and spring joining place, spring 3 is fixed on the fixed mount 2, also can be fixed on the fixed mount 2 by an electrode holder spring 3 by rivet.
The utility model can change the front and rear angles of headrest by helical spring elastic deformation, makes the mobility and flexibility of head increase, and reduces the fatigue of head and neck, improves the traveling comfort of taking, and has also protected driving staff's head and neck simultaneously effectively.
