Description

Automobile seat arm

Technical field

The utility model belongs to vehicular spare parts, relates to armrest, specifically a kind of automobile seat arm in car.

Background technology

The handrail of most of automotive seat can keep flat or upwards rise to vertical position, the unadjustable angle of lifting to other; The automobile seat arm also having adopts the angle of escapement adjustable handrail, but the automobile seat arm of this class structurally comprises the matrix being fixedly installed and the movable arm that can rotate with respect to described matrix along horizontal axis, after movable arm raises, must there is a drag link mechanism to come ratchet and pawl manual unlocking, can keep flat playback, therefore use inconvenience.

Summary of the invention

The technical problems to be solved in the utility model, is to provide a kind of automobile seat arm, can regulate and lift angle Reversion Level position.

For solving the problems of the technologies described above, technical solution adopted in the utility model is:

A kind of automobile seat arm, comprise the matrix being fixedly installed and the movable arm that can rotate with respect to described matrix along horizontal axis, on matrix, be provided with ratchet, be provided with the ratchet that is positioned at above ratchet, coordinates with ratchet on movable arm, described ratchet can rotate around the rotation axis of movable arm; On matrix, be provided with the first block and the second block that are positioned at ratchet both sides, restriction ratchet rotational angle; On matrix, be also provided with the arc that is parallel to ratchet, when movable arm upwards rotates, described ratchet can contact with arc and can be lifted away from ratchet by arc, on ratchet, be provided with the arcuate furrow of one section of sealing, on movable arm, be provided with the finger that inserts arcuate furrow, ratchet is lifted away from after ratchet by arc, and described finger can be stirred arc and rotate in company with movable arm.

As to restriction of the present utility model, described movable arm is provided with the push rod for driving ratchet and ratchet to depart from.

As to another kind of restriction of the present utility model, on matrix, be provided with the torsion spring that compresses described the first block and the second block for promoting ratchet.

The utility model also has a kind of restriction, is provided with the spring for ratchet being compressed to ratchet on matrix.

Owing to having adopted above-mentioned technical scheme, compared with prior art, obtained technological advance is the utility model:

Automobile seat arm provided by the utility model, can separate ratchet and pawl by arc, thereby avoid the impact of ratchet on movable arm, and movable arm is playbacked smoothly; Push rod is set and can prevents unexpected stuck cannot the operation of ratchet device, improve the reliability of this automobile seat arm, and can make movable arm depart from an arbitrary position click restriction, it is freely rotated; Torsion spring is set ratchet is compressed, can improve the stability of movable arm; Spring application ratchet is set, can improves the reliability of ratchet.

The utility model is applicable to, on the products such as various vehicles and furniture, match with seat main body.

The utility model is described in further detail below in conjunction with Figure of description and specific embodiment.

In figure: 1, matrix; 2, movable arm; 3, ratchet; 4, ratchet; 5, the first block; 6, the second block; 7, arc; 8, arcuate furrow; 9, finger; 10, push rod; 11, torsion spring.

The specific embodiment

Embodiment

As shown in Figure 1 to Figure 3, the present embodiment is a kind of automobile seat arm, it comprises the matrix 1 being fixedly installed and the movable arm 2 that can rotate with respect to matrix 1 along horizontal axis, is provided with ratchet 3 on matrix 1, is provided with the ratchet 4 that is positioned at above ratchet 3, coordinates with ratchet 3 on movable arm 2.

In order to make movable arm 2 automatically return to horizontal position, the present embodiment also arranges corresponding mechanism and drives ratchet 4 automatically to separate with ratchet 3.Ratchet 3 rotates take the rotation axis of movable arm 2 (be movable arm 2 rotated when cocked axis) as rotation axis, such as: the rotating shaft being rotationally connected with movable arm 2 is set on matrix 1, movable arm 2 can rotate along this rotating shaft, ratchet 3 is connected in rotating shaft, like this, ratchet 3 just can be realized above-mentioned rotation.On matrix 1, be provided with and be positioned at ratchet 3 both sides and for limiting the first block 5 and second block 6 of ratchet 3 rotational angles; On matrix 1, be also provided with the arc 7 that is parallel to ratchet 3.When movable arm 2 upwards rotates, ratchet 4 can contact with arc 7 and can be lifted away from ratchet 3 by arc 7, on ratchet 3, be provided with the arcuate furrow 8 of one section of sealing, on movable arm 2, be provided with the finger 9 that inserts arcuate furrow 8, ratchet 4 is lifted away from after ratchet 3 by arc 7, and finger 9 can be stirred arc 7 and rotate in company with movable arm 2.

On matrix 1, be provided with torsion spring 11, torsion spring 11 can promote ratchet 3 and compress all the time the first block 5 or the second block 6, thereby can prevent ratchet 3 plaies.

On matrix 1, be provided with the spring that ratchet 4 is compressed to ratchet 3, on movable arm 2, be provided with the push rod 10 that drives ratchet 4 and ratchet 3 to depart from, in the time of ratchet 3 clamping stagnation, can drive ratchet 4 and its release with push rod 10, guarantee that this automobile seat arm can normally use.

In use, movable arm 2 can be kept flat to support driver and conductor's arm, and it can be made shaft-like or be made as the forms such as the cover plate of armrest box.The present invention is applicable to handrail series products, and the cover plate opening angle that can be used for again case series products regulates.

As shown in Figure 2, when, relying on ratchet 3 and ratchet 4 that movable arm 2 is fixed on to this angle, thereby adapt to occupant's difference needs upwards after cocked movable arm 2 certain angles with hand; If continue upwards to pull movable arm 2, ratchet 4 will touch arc 7 so, ratchet 4 is lifted away from ratchet 3 by arc 7, then, finger 9 contacts with a lateral edges of arcuate furrow 8, start to promote ratchet 3 and rotate in company with movable arm 2, in the time turning over certain angle, ratchet 3 is subject to the effect of torsion spring 11 and is pressed on the

second block

6, and 2 of movable arms can rise to extreme higher position.

In the time putting down movable arm 2, first ratchet 4 is followed movable arm 2 and is moved downward, now it can not contact with ratchet 3, when ratchet 4 drops to certain altitude, finger 9 can contact with the opposite side of arcuate furrow 8, drive ratchet 3 to rotate until ratchet 3 is pressed on the first block 5, now movable arm 2 is in horizontality.
