The self-locking structure of the folding headrest comprises a left lug cover plate 1, a movable pinch plate 6 and an angle locating plate 7 with a tooth groove 8, the angle locating plate 7 is connected with the lower half portion of the left lug cover plate 1 through a main shaft 11, the movable pinch plate 6 is positioned above the angle locating plate 7, one end of the movable pinch plate 6 is connected with the left lug cover plate 1 through a pin shaft 12, and the other end of the movable pinch plate 6 contacts with the upper edge of the angle locating plate 7. The self-locking structure of the folding headrest is characterized by further comprising an inertia rod 3, a small torsional spring 2 and a small riveting pin 5, a riveting hole 10 is formed in the inertia rod 3, one end of the small riveting pin 5 penetrates through the riveting hole 10 and the small torsional spring 2 in sequence and is connected with the left lug cover plate, one end of the small torsional spring 2 is hooked to the inertia rod 3, the other end of the small torsional spring 2 is propped on the side face of the left lug cover plate 1, and the bottom 9 of the inertia rod 3 is positioned above the tooth groove 8 of the angle locating plate 7.
Description
Technical field
The utility model relates to a kind of automotive headrest, particularly discloses the self-locking structure on a kind of folding headrest.
Background technology
At present, the headrest that band on some automotive seat is folding, increase various parts at headrest, to realize folder function, but when automobile when emergency brake or headrest have forward force of inertia effect, headrest is can be automatically folding forward, causes the rider to run into unintentionally to cause discomfort or the rider is damaged.
Summary of the invention
Headrest was subjected to the effect of force of inertia cause the resting the head on shortcoming of auto-folder when the purpose of this utility model was to overcome automobile emergency brake in the prior art, and the self-locking structure on a kind of easy to use, low noise, the safe and reliable folding headrest is provided.
The utility model is achieved in that the self-locking structure on a kind of folding headrest, comprise left ear cover plate 1, movable buckle plate 6, angle orientation plate 7 with teeth groove 8, described angle orientation plate 7 links to each other with the latter half of described left ear cover plate 1 by main shaft 11, described movable buckle plate 6 is positioned at the top of described angle orientation plate 7, one end of described movable buckle plate 6 links to each other with left ear cover plate 1 by bearing pin 12, the other end of movable buckle plate 6 contacts with the upper limb of angle orientation plate 7, it is characterized in that: also comprise inertia rod 3, little torsion spring 2, little riveting pin 5, described inertia rod 3 is provided with riveted holes 10, one end of described little riveting pin 5 passes riveted holes 10 successively, little torsion spring 2 also links to each other with left ear cover plate, one end of described little torsion spring 2 catches on described inertia rod 3, and the other end of little torsion spring 2 is supported on the side of left ear cover plate 1; The bottom 9 of described inertia rod 3 is positioned at the top of the teeth groove 8 of angle orientation plate 7.
The path of motion of described inertia rod 3, movable buckle plate 6 and angle orientation plate 7 is in same plane.
Cover has cushion collar 4 on the described inertia rod 3.
The beneficial effects of the utility model are: when headrest when being subject to the preshoot force of inertia, the inertia rod in the self-locking structure is had an effect, the bottom of inertia rod contacts with teeth groove in the angle orientation plate, reaches the purpose that headrest is folded forward.
Description of drawings
Fig. 1 is the utility model blast structural representation.
Fig. 2 is the utility model virgin state construction profile scheme drawing.
Fig. 3 is the construction profile scheme drawing after the action of the utility model inertia rod.
Wherein: 1, left ear cover plate; 2, little torsion spring; 3, inertia rod; 4, cushion collar; 5, little riveting pin; 6, movable buckle plate; 7, angle orientation plate; 8 teeth groove; 9, bottom; 10, riveted holes; 11, main shaft; 12, bearing pin.
The specific embodiment
According to Fig. 1~Fig. 3, the utility model comprises left ear cover plate 1, movable buckle plate 6, with the angle orientation plate 7 of teeth groove 8, draw together inertia rod 3, little torsion spring 2, little riveting pin 5, described angle orientation plate 7 links to each other with the latter half of described left ear cover plate 1 by main shaft 11, described movable buckle plate 6 is positioned at the top of described angle orientation plate 7, one end of described movable buckle plate 6 links to each other with left ear cover plate 1 by bearing pin 12, and the other end of movable buckle plate 6 contacts with the upper limb of angle orientation plate 7; Described inertia rod 3 is provided with riveted holes 10, one end of described little riveting pin 5 passes successively riveted holes 10, little torsion spring 2 and links to each other with left ear cover plate, described little torsion spring 2 is positioned at the centre of left ear cover plate 1 and inertia rod 3, one end of described little torsion spring 2 catches on described inertia rod 3, and the other end of little torsion spring 2 is supported on the side of left ear cover plate 1; The bottom 9 of described inertia rod 3 is positioned at the top of the teeth groove 8 of angle orientation plate 7.The path of motion of described inertia rod 3, movable buckle plate 6 and angle orientation plate 7 is in same plane.On the described inertia rod 3 cover have cushion collar 4, described cushion collar 4 be for prevent inertia rod 3 when action with left ear cover plate 1 and movable buckle plate 6 generation grazings and produce noise.
When the utility model when virgin state is not subject to External Force Acting, little torsion spring 2 is in open configuration, inertia rod 3 is owing to be subject to the effect of little torsion spring 2 and contact with movable buckle plate 6 all the time; When the utility model is subject to the preshoot force of inertia, inertia rod 3 is subject to inertia effect forward simultaneously, this moment inertia rod 3 with little riveting pin 5 as the instantaneous rotation of fulcrum generation anticlockwise direction, the bottom 9 of the inertia rod 3 on inertia rod 3 lower parts turns in the teeth groove 8 of angle orientation plate 7, thereby stopped the rotation of angle orientation plate 7, thereby reached the purpose that headrest is folded forward.When not having External Force Acting, inertia rod 3 is because the effect of little torsion spring 2 automatically reverts to open configuration.
