Description

  The present invention relates to a headrest holder used for mounting a headrest of an automobile seat.

Normally, in automobiles, the headrest is inserted into the left and right tubular guide brackets welded to the frame top of the seat back frame, and the left and right tubular headrest holders are inserted into the left and right tubular headrest holders. -It is common to adopt a structure in which the stays are inserted in a corresponding manner and are attached to the seat back so that the height can be adjusted and secured.
The headrest holder has an elastic claw and hooks the elastic claw on the notch of the stylus to prevent the stylus from falling out, resulting in a gap between the headrest holder and the guide bracket There was a problem that noise was not absorbed and abnormal noise was generated.

  An object of the present invention is to prevent rattling caused by a gap between the guide holder and the headrest stay, to avoid the generation of abnormal noise, and to prevent the stay from coming off. To provide a tubular headrest holder.

  The present invention has a headrest / sti insertion opening opened at both ends, the holder head is formed so as to be able to incorporate a stay / lock mechanism at one of its both ends, and an elastic presser claw with a retaining function Is protruded to the outer peripheral surface in a state of being cut into the end portion at a position enabling to correspond to the retaining notch of the headrest stay at the other end of the both ends, and inserted into the guide bracket of the seat back and held, Insert the headrest stay and adjust the height of the headrest.

  In this invention, when the headrest holder is inserted into the guide bracket, the elastic force is applied to return to the outside at the nail root bending point of the presser pawl, and the gap between the guide bracket and the head bracket is applied. The headrest holder is urged to insert the stay of the headrest and return to the inside at the bending point of the claw tip of the presser claw in normal use. When the stick is pulled out of the headrest holder and the height is adjusted, and the headrest is prevented from coming off, the claws are prevented. The elastic claw claw tip urged at the tip bending point is caught by the retaining notch of the stay, and the headrest is removed. There is prevented.

  The tubular headrest holder has a headrest stick insertion opening opened at both ends, the holder head is formed so that a stick lock mechanism can be incorporated at one end of the holder head, and has an elastic structure with a retaining function. The presser claw protrudes to the outer peripheral surface in a state of being cut into the end at a position enabling the presser claw to correspond to the retaining notch of the headrest stick at the other end, and is inserted into the guide bracket of the seat back and held. The height of the headrest can be adjusted and secured by inserting the headrest stay. Then, it is desirable that the elastic presser claw with a retaining function bends the nail root side toward the presser bending part and the nail tip side to the retaining bent part.

  Hereinafter, the tubular headrest holder according to the present invention will be described based on the specific example shown and illustrated. FIGS. 1 to 6 are used for mounting a headrest of a driver seat (not shown) of a passenger car. However, an embodiment 10 of the tubular headrest holder of the present invention is shown, and the driver seat welds the left and right tubular guide brackets 20, 20 to the frame top of the seat back frame. The left and right tubular headrest holders 10 and 10 are correspondingly inserted into the left and right tubular guide brackets 20 and 20, and the left and right tubular headrest holders 10 and 10 are inserted into the left and right tubular headrest holders 10 and 10, respectively. And adjust the height of the headrest to the seat / back. And it has adopted the retainer can be attached at the structure.

  The tubular headrest holder 10 has headrest / stay insertion ports 11 and 12 opened at both ends, and the holder head 13 is formed so that a stay lock mechanism (not shown) can be incorporated at one of the both ends. In addition, the elastic presser pawl 14 with a retaining function is cut into the end portion at the position where the other end of the elastic gripping pawl 14 can correspond to the retaining notch 31 of the pipe stay 30 and cut to the outer peripheral surface. Then, it is inserted and held in the guide bracket 20 of the seat back, the pipe stay 30 is inserted, and the headrest is attached to the seat back so that the height can be adjusted and removed.

  The elastic presser pawl 14 with a retaining function is projected to the outer peripheral surface (outer side surface) in a cut state at the lower end portion of the headrest holder 10, and the presser bent portion with the nail root bending point A at the base of the nail base 15, the nail tip bending point B is bent at the nail tip bending point B so as to be bent into the bent portion 16. As shown in FIG. 3, the retaining bent portion 16 is substantially on the outer surface of the headrest holder 10 from the presser portion 15 at the claw tip bending point B, that is, on the outer surface of the lower end portion. It is bent in parallel.

  In the headrest holder 10, the fixing structure to the guide bracket 20 and the headrest height adjusting lock structure, that is, the stay lock mechanism is based on the conventional technology, and thus the description thereof is omitted.

  Therefore, when the headrest holder 10 is inserted into the guide bracket 20 as shown in FIG. 4, the elastic force is applied to return outward at the nail root bending point A of the presser pawl 14. , And the headrest holder 10 is inserted into the stay 30 of the headrest as shown in FIG. The presser claw 14 is biased to return inward at the claw tip bending point B, and rattling between the stay 30 and the stay 30 is prevented, so that the generation of abnormal noise is avoided. 6 is pulled out from the headrest holder 10 as shown in FIG. 6 to adjust the height, and when the headrest is prevented from coming off, it is attached at the bending point B of the claw tip. Been claw end 17 of the holding pawl 14 to its elasticity is is caught in the retaining notch 31 of the stay 30, and, omission of the headrest can be prevented.

  As will be apparent from the specific embodiments of the present invention described above with reference to the drawings, for those of ordinary skill in the art to which the present invention pertains, It is easily embodied in another embodiment that derives from the nature and nature of the invention and that is objectively recognized as having them inherent. Of course, the content of this invention corresponds to the problem of the invention (be recommend with) and is essential for the establishment of the invention.

  As can be understood from the above, the tubular headrest holder of the present invention has a headrest / sti insertion opening opened at both ends, and the holder head is formed so that a stay lock mechanism can be incorporated at one of the both ends. And an elastic gauze claw with a retaining function is projected to the outer peripheral surface in a state of being cut into the end portion at a position that allows the other end of the retaining claw to correspond to the retaining notch of the headrest stay, and the sheet The tubular headrest holder of the present invention is inserted into and held by the guide bracket of the back, and the headrest stay can be inserted to adjust the height and prevent the headrest from being removed. The rattling caused by the gap between the headrest stay and the headrest stay is prevented, and abnormal noise is reduced. It is, and the stay is prevented loss, as a result, it is very useful and practical for the vehicle seat.

It is the perspective view which showed the specific example of the tubular headrest holder of this invention utilized for the headrest attachment of the driver | operator seat of a passenger car. It is the fragmentary perspective view which showed partially the stay of the headrest. It is the fragmentary longitudinal cross-sectional view which showed the lower end part of the headrest holder in cross section. It is the fragmentary longitudinal cross-section which cut and showed those lower end parts in the state which inserted the headrest holder in the guide bracket. It is the fragmentary longitudinal cross-section which showed the headrest holder in the normal use state. It is the fragmentary longitudinal cross-section which showed the headrest holder in the headrest removal prevention state.
