Abstract
The invention relates to a seat backrest framework with a movable headrest, comprising a headrest framework and a backrest framework. The headrest framework consists of a headrest sleeve and a movable headrest rod; wherein, the movable headrest rod is movably arranged in the headrest sleeve which is internally provided with an unlocking/locking mechanism for the movable headrest rod; the headrest sleeve is fixed on the backrest framework. The unlocking/locking mechanism comprises a button, a lock tongue and a spring; the button is connected into a whole with one end of the lock tongue; the other end of the lock tongue is pushed by one end of the spring; the other end of the spring is fixed in the internal wall of the headrest sleeve; furthermore, the rod wall of the movable headrest rod is provided with a locking trough matched with the lock tongue. The seat backrest framework is designed with the movable headrest framework, thus leading the height of the headrest to be adjustable, well meeting the requirement of the new regulation without changing the basic structure of the original seat backrest framework, and increasing the safety of a seat by leading a passenger to find suitable position for supporting the head.
Description
Technical field
The invention belongs to the automotive seat technical field.
Background technology
At present the headrest of some seat back-rest frameworks is fixing, and headrest is with the backrest foaming, though accomplished that cost is low, simple in structure, also exist deficiencies such as of low grade, poor stability on the other hand.Bigger with stylish rules to chair headrest requirement for height increase rate; the height of headrest of back seat requires to have improved 100mm; the increase of height of headrest be for collision after the better protection for the protection of neck, this product influence for design typification is bigger.
Summary of the invention
The objective of the invention is to deficiency, propose a kind of seat back-rest framework, strive for that with the design modification of minimum existing procucts had both met rules and the change expense is minimum with active head restraint at the prior art existence.
The technical solution used in the present invention is as follows:
A kind of seat back-rest framework, it includes headrest skeleton and backrest skeleton, the skeleton that it is characterized in that resting the head on is made up of headrest sleeve and movable head restraint bar, wherein the movable head restraint bar is movably arranged in the headrest sleeve, the unlocking/locking locking mechanism of pair movable head restraint bar is arranged in the headrest sleeve, and headrest sleeve is fixed on the backrest skeleton.
The parts of described unlocking/locking locking mechanism comprise button, dead bolt and spring, one end of button and dead bolt is connected as a single entity, one end of the other end of dead bolt and spring offsets, the other end of spring is fixed in the inside pipe wall of headrest sleeve, in addition, the bar wall of movable head restraint bar is provided with the lock groove that cooperates with dead bolt.
Position at backrest skeletal fixation headrest sleeve is provided with the load steel pipe, and headrest sleeve is fixed on the load steel pipe.
This seat back-rest framework becomes movable by the frame design of will resting the head on, make height of headrest adjustable, under the prerequisite that does not change original chair backrest skeleton basic structure, can satisfy new legislation preferably requires the R point highly to be greater than the requirement of 750mm to headrest, can allow the passenger seek the correct position supporting head part, increase the safety of seat.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the outside drawing of skeleton of wherein resting the head on;
Fig. 3 A is the structural representation of skeleton the first half of wherein resting the head on;
Fig. 3 B is the structural representation of headrest skeleton the latter half.
The specific embodiment
The concrete structure of the movable headrest of this integral type backrest is seen Fig. 1, and it is made of jointly headrest skeleton 1, backrest skeleton 2, load steel pipe 3 and connection hook 4 etc.Referring to Fig. 2, the skeleton 1 of wherein resting the head on is made up of headrest sleeve 11 and movable head restraint bar 12, forms active head restraint and can realize resting the head on up and down.Movable head restraint bar 12 scribbles grease and passes headrest sleeve 11, be movably arranged in the headrest sleeve 11, the unlocking/locking locking mechanism that pair movable head restraint bar 12 is arranged in the headrest sleeve 11, after headrest sleeve 12 releases, movable head restraint bar 12 can slide up and down, the passenger finds comfortable position according to self-condition adjustment headrest skeleton 1 height.Fixedly be provided with load steel pipe 3 in the position of headrest sleeve 11 at backrest skeleton 2, headrest sleeve 11 is fixed on the load steel pipe 3, and load steel pipe 3 will be rested the head on, and institute is stressed to be assigned on the vehicle body fifty-fifty.Connect the both sides that hook 4 is fixed on backrest skeleton 2, whole backrest is bound up on the vehicle body, so backrest skeleton 2 supports human body backrest pressure.
Referring to Fig. 3 A and Fig. 3 B, the parts of the unlocking/locking locking mechanism of headrest skeleton 1 comprise button 13, dead bolt 14 and spring 15, button 13 is connected as a single entity with an end of dead bolt 14, one end of the other end of dead bolt 14 and spring 15 offsets, the other end of spring 15 is fixed in the inside pipe wall of headrest sleeve 11, in addition, the bar wall of movable head restraint bar 12 is provided with the locking skewed slot 16 that cooperates with dead bolt.When pressing button 13, dead bolt 14 presses institute's springs to withdraw from locking skewed slot 16, after movable head restraint bar 12 upwards slides into locking skewed slot 16, dead bolt 14 carve under spring 15 effects close into another locking skewed slot 16 after, movable head restraint bar 12 lockings promptly being finished headrest and regulating.
