The technical scheme in the invention for solving the technical problem is:
A kind of automotive seat four-way headrest, comprise head pillow frame and foaming assembly, described head pillow frame comprises the longitudinally guide rod of setting and the strut bar for supporting head part, described strut bar can rotate relative to described guide rod fore-and-aft direction, it is characterized in that: the top of described guide rod is fixed with spacing lever, described spacing lever is set to frame-type, described strut bar includes headrest portion and connecting portion, in the frame-type space that described connecting portion wears spacing lever and the front side lever of the both sides, front and back of limited pin and rear side lever institute spacing, the upper lateral of described guide rod is provided with adapter shaft, described connecting portion is connected on the adapter shaft of described headrest guide rod by holddown spring clamping, and can rotate relative to described adapter shaft.
As preferably, the left and right sides of spacing pin is set to scalable socket join structure.
As preferably, connecting portion outsourcing is provided with plastic cover.
As preferably, guide rod comprises the first guide rod and the second guide rod that are positioned at the left and right sides, the first described guide rod and the upper end of the second guide rod are established to antecurvature, and between the first guide rod and the second guide rod, being connected with the anchor shaft being parallel to adapter shaft, described front side lever is fixedly connected on described anchor shaft.
As preferably, the upper end of connecting portion turns over the headrest portion established described in formation downwards.
As preferably, on first guide rod, the second guide rod respectively sheathed can relative sliding have in the first leader casing and the second leader casing, the first described guide rod and the second guide rod offer position-limited trough respectively, the first described leader casing and the second leader casing arrange the limit locking pieces that can embed position-limited trough respectively, and described limit locking pieces connects button by spring.
Headrest can realize sliding up and down by guide rod, the fore-and-aft direction of headrest rotates through strut bar to realize, because the connecting portion of strut bar is connected on adapter shaft by holddown spring clamping, as long as therefore pull headrest, just can realize it to seesaw, and holddown spring can realize step-less adjustment, the friction force of the compacted rear generation of holddown spring, headrest strut bar can be made to remain on optional position in stroke, thus realize step-less adjustment function.During rotation, because connecting portion is located in the frame-type space of spacing lever, then turn to certain position, will the front side lever of limited lever and rear side lever institute spacing, the stroke namely rotated before and after constraint headrest.And restraining position can be regulated by the scalable socket join structure of spacing lever.Plastic cover is provided with in connecting portion outsourcing, the metal parts of band sharp edge covers by plastic cover, passenger is arranged after can avoiding the metal sharp edge injury given prominence to, when particularly colliding, rear row's passenger position likely head that moves forward bumps against front headrest, now plastic cover can avoid back occupant head impact to metal sharp edge, effectively can reduce the injured degree of occupant.
The up-down adjustment of headrest is regulated by the first guide rod, the second guide rod, and during adjustment, button press, the headrest that slides is to desired location, then release-push, then limit locking pieces is embedded in position-limited trough, then realize locking, up-down adjustment.
To be that connecting portion upper end is curved downwards establish formation in headrest portion, for supporting occupant's head, along with connecting portion realizes rotating together.
The beneficial effects of the utility model are: the spacing lever that the utility model passed through frame-type realizes, and adjustable limit stroke, structure is more reasonable reliable, and can realize step-less adjustment.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Fig. 1,2,3,4,5, a kind of automotive seat four-way headrest, comprise head pillow frame and foaming assembly, described head pillow frame comprises the longitudinally guide rod 6 of setting and the strut bar for supporting head part, described strut bar includes headrest portion 1 and connecting portion 4, and the upper end that headrest portion 1 is connecting portion is turned over downwards and established formation, strut bar can rotate relative to described guide rod 6 fore-and-aft direction.The top of guide rod is fixed with spacing lever 5, described spacing lever 5 is set to frame-type, in the frame-type space that connecting portion 4 wears spacing lever 5 and the front side lever 2 of the both sides, front and back of limited pin and rear side lever 3 institute spacing, the upper lateral of described guide rod is provided with adapter shaft 9, described connecting portion is connected on the adapter shaft 9 of described headrest guide rod by holddown spring 8 clamping, and can rotate relative to described adapter shaft 9.The left and right sides of spacing pin is set to scalable socket join structure.Stroke then between front side lever 2 and rear side lever 3 adjusts by regulating this scalable socket join structure.Connecting portion outsourcing is provided with plastic cover.
Guide rod 6 comprises the first guide rod 10 and the second guide rod 11 being positioned at the left and right sides, the first described guide rod and the upper end of the second guide rod are established to antecurvature, and between the first guide rod and the second guide rod, being connected with the anchor shaft 12 being parallel to adapter shaft, described front side lever is fixedly connected on described anchor shaft 12.On first guide rod, the second guide rod respectively sheathed can relative sliding have in the first leader casing 14 and the second leader casing 13, the first described guide rod and the second guide rod offer position-limited trough 16 respectively, the first described leader casing and the second leader casing arrange the limit locking pieces 15 that can embed position-limited trough respectively, and described limit locking pieces connects button 17 by spring.
Headrest can realize sliding up and down by guide rod 6, the fore-and-aft direction of headrest rotates through strut bar to realize, because the connecting portion 4 of strut bar is connected on adapter shaft 9 by holddown spring 8 clamping, as long as therefore pull headrest, just can realize it to seesaw, and holddown spring can realize step-less adjustment, the friction force of the compacted rear generation of holddown spring, headrest strut bar can be made to remain on optional position in stroke, thus realize step-less adjustment function.During rotation, because connecting portion is located in the frame-type space of spacing lever 5, then turn to certain position, will the front side lever 2 of limited lever and rear side lever 3 institute spacing, the stroke namely rotated before and after constraint headrest.And restraining position can be regulated by the scalable socket join structure of spacing lever.Plastic cover 7 is provided with in connecting portion outsourcing, the metal parts of band sharp edge covers by plastic cover, passenger is arranged after can avoiding the metal sharp edge injury given prominence to, when particularly colliding, rear row's passenger position likely head that moves forward bumps against front headrest, now plastic cover can avoid back occupant head impact to metal sharp edge, effectively can reduce the injured degree of occupant.
The up-down adjustment of headrest is regulated by the first guide rod 10, second guide rod 11, and during adjustment, button press, the headrest that slides is to desired location, then release-push, then limit locking pieces is embedded in position-limited trough, then realize locking, up-down adjustment.
