Abstract
The utility model discloses a moving head-rest for a vehicle seat. The utility model is mainly characterized in that a pillow pole is movably connected with a skeleton of the head-rest, and an angle regulator which can drive the skeleton to rotate relatively to the pillow pole is equipped. The angle of the head-rest of the utility model can be adjusted, thus the head-rest more conforms to the requirement of the human engineering; by means of adjustment, the head-rest can be kept in favorable amenity all the time.
Description
The utility model relates to a kind of headrest, particularly relates to a kind of active head restraint that is loaded on its headrest adjustable angle on the automotive seat.
Present headrest, as the headrest that uses on the automotive seat, its pillow bar and skeleton generally adopt modes such as welding affixed, thereby its headrest angle is changeless.Generally speaking, different people or same people are that different the requirement arranged in the different stage (as physiological stage, travelling stage) to the headrest angle, headrest fixed angle unmodified headrest just can not satisfy this diverse requirement, and its traveling comfort just is difficult to be guaranteed.
Given this, the purpose of this utility model provides a kind of active head restraint that can change its headrest angle with the need.
The purpose of this utility model is achieved in that in the headrest of elastic filler with pillow bar, skeleton, coating skeleton and mask, will rest the head on bar and be actively connected on the skeleton, and the recliner that can drive the skeleton rotation is set in headrest.Transfer recliner, skeleton can be with respect to the rotation forward or backward of pillow bar do, and skeleton drives elastic filler and mask together rotates, thereby reaches the purpose of headrest adjustable angle.
Specifically, above-mentioned skeleton is to adopt framed structure, above-mentioned recliner by activity be connected on the skeleton screw mandrel and the band spiral chute conduit and form with screw mandrel, conduit plug helix nut engaged respectively, wherein nut top has tapped bore, screw mandrel be pass nut thread and with people's nut engagement, the plug helix of cylinder and conduit fits in cam mechanism under the nut; Above-mentioned pillow bar and conduit are affixed, and described screw mandrel outer end is provided with handle.When angle need be adjusted, hold the handle rotary screw rod, screw mandrel rotates the drive nut and moves, and cylinder just moves in the spiral chute of conduit under the nut; Because band spiral fluted conduit is connected as a single entity with the pillow bar, the pillow bar is inserted in the back of seat again, so conduit maintains static, therefore when cylinder under the nut is mobile in the conduit plug helix, nut just promotes screw mandrel, and then the headrest skeleton is rotated forward or backward, and the headrest angle is adjusted thus.
Above-mentioned skeleton by base plate and the left and right support plate that is connected to the base plate two ends respectively constitute, all have screw mandrel, conduit mounting hole on the left and right support plate.Above-mentioned screw mandrel and conduit are movably arranged on the respective aperture on the left and right plate.
On the above-mentioned conduit torsion spring is housed, one of torsion spring terminates on the skeleton, and the other end is connected on the pillow bar.When above-mentioned skeleton during in the rotation of doing with respect to pillow bar (and conduit) forward or backward, be loaded on supravasal torsion spring and can play good shock damping action, make the skeleton rotary balance.
Be connected to lower cover in above-mentioned base plate bottom, left and right support plate upper end is connected to upper cover plate, is connected with connecting panel in the inboard that is positioned at right supported plate on the base plate, and described right supported plate direct connection is on connecting panel.The setting of connecting panel can make things convenient for the installation of recliner.
Elastic filler of the present utility model is a contoured foam.
The utility model and existing fixed angle headrest is compared, and has good preceence, and as mentioned above, its headrest adjustable angle more can meet ergonomic needs, can keep good comfort all the time, these be fixed angle rest the head on can not or unapproachable.
Further specify the utility model below in conjunction with drawings and Examples
Fig. 1 is the utility model structural representation
Fig. 2 is Figure 1A-A cutaway view
Fig. 3 is the left socle constructional drawing
The utility model active head restraint (seeing Fig. 1,2) has mask 1, contoured foam 2, skeleton 3, pillow bar 4; Skeleton 3 is a framed structure, constitute by base plate 5 and left and right support plate 6,7, left supported plate 6 is welded on the base plate, be welded with connecting panel 19 on the base plate 5, right supported plate 7 is by three of screw 18() be connected on the connecting panel 19, all have screw mandrel mounting hole 18 on the left and right support plate and conduit mounting hole 9(sees Fig. 3), also have spring connecting hole 10 on the left supported plate 6; On a left side, be movably installed with screw mandrel 11 on the right supported plate and conduit 12(sees Fig. 1,2), the outer end of screw mandrel 11 is connected to handle 14 by tightening screw 13, the tapped bore engagement that leave on screw thread on the screw mandrel 11 and nut 15 tops, have spiral chute 16 on the conduit 12,15 times cylinders of nut and conduit plug helix 16 fit in cam mechanism, the size of conduit spiral fluted helical angle should satisfy self-locking requirement, have pillow bar hole on the conduit 12, pillow bar 4 passes pillow bar hole and is welded on the conduit 12, torsion spring 17 is housed on the conduit 12, one of torsion spring 17 terminates on the spring connecting hole 10 on the left supported plate 6, the other end of torsion spring 17 is connected on the pillow bar 4, above-mentioned screw mandrel 11, conduit 12, nut 15 is formed the distinctive headrest recliner of the utility model; Be connected with upper cover plate 20 on the left and right support plate 6,7, base plate 5 bottoms are connected with lower cover 22 by screw 21, all have the bar shape trench hole 23 that penetrates for pillow bar 4 on base plate 5 and the lower cover 22.The utility model in use, screw mandrel 4 is inserted on the back of seat, when needs are adjusted the headrest angle, turning handle 14 rotates screw mandrel 11, screw mandrel 11 rotates drive nut 15 and moves, when in the spiral chute 16 of 15 times cylinders of nut at conduit 12 when mobile, nut 15 promotes screw mandrel 11, and then make skeleton 3 rotate (because conduit 12 maintains static with pillow bar 4) forward or backward, this rotation of 17 pairs of skeletons 3 of torsion spring plays shock damping action, makes the skeleton stability of rotation, because the helical angle of plug helix 16 is less, after skeleton 3 rotated under external force and stops, whole recliner can play self-locking action.Adjustable angle scope of the present utility model is ± 30 °.Theoretically, the headrest angle of regulation range is positive magnitude relation with conduit plug helix length to a certain extent, but from the angle of ergonomic, regulate ± 30 ° enough, can guarantee good comfort.
