As shown in FIG. 1, the vehicle seat assist grip 100 according to the embodiment includes a grip 10 and an attachment member 20.

  The grip 10 is formed by bending a cylindrical pipe into a U shape or a C shape. The grip portion 11 (J-shaped portion) that is gripped by a human being is covered with a foamable resin, cloth, or the like, and has a good touch and is easy to grip. In the remaining portion, the internal pipe is exposed and, as shown in FIG. 2, a plurality of grooves 12 parallel to the longitudinal direction of the grip 10 are provided.

  The mounting member 20 includes a grip fixing means 30 for fixing the grip 10 by inserting the grip 10, and a support pole fixing means 40 for fixing the support pole 51 by inserting the support pole 51 (see FIG. 6) of the headrest 50. The fixing means 30 and 40 are provided adjacent to each other (see FIGS. 1 and 3).

  As shown in FIG. 3, the grip fixing means 30 is provided in a grip insertion portion 31 formed by an insertion hole into which the grip 10 is rotatably inserted, and a part of a wall portion 31 a of the grip insertion portion 31. And a pressing adjusting member 33 that presses inwardly of the pressing member 32.

  The grip insertion portion 31 is formed by an insertion hole having an inner diameter that is the same as or slightly larger than the diameter of the cross section of the grip 10 provided at the approximate center of the mounting member 20. (See B in FIG. 1). A substantially rectangular through hole 31b (see FIG. 5) to which a pressing member 32 described later is attached is formed in at least a part of the wall portion 31a of the grip insertion portion 31.

  As shown in FIGS. 4 and 5, the pressing member 32 forms a substantially rectangular parallelepiped having substantially the same size as the through hole 31 b of the mounting member 20. When the pressing member 32 is mounted on the mounting member 20, the grip insertion portion The inner side surface 32a located on the wall 31a side of the 31 is formed in a concave shape so as to draw an arc similar to the arc of the cross-sectional circle of the grip insertion portion 31. Further, a protrusion 32b is formed on the inner side surface 32a so as to protrude along the longitudinal direction so as to be fitted to the plurality of grooves 12 of the grip 10. On the other hand, the outer side surface 32c opposite to the inner side surface 32a is similarly formed in a concave arc. The curvature of the arc is set regardless of the curvature of the inner side surface 32a. Furthermore, at least a part of the side surface of the pressing member 32 is provided with an urging member 32d that is formed to project from the corner portion 32e on the outer side surface 32c side. The urging member 32d is made to have a restoring force when the angle of the root portion 32e with the main body of the pressing member 32 is changed or when the urging member 32d itself is bent. The pressing member 32 thus manufactured is fitted into a through hole 31b provided in the wall portion 31a of the grip insertion portion 31. The inserted pressing member 32 can move inward or outward (E or F) in the through hole 31b. Further, the biasing member 32d is in contact with a part of the mounting member 20, and is biased outward by the restoring force of the biasing member 32d. Therefore, after moving inward by an external force, if the external force is eliminated, it moves in the outward direction.

  As shown in FIGS. 3 and 5, the pressing adjustment member 33 has a substantially cylindrical body 33 a, an operation piece 33 b for manually rotating the side surface of the substantially cylindrical body 33 a, and for restricting the rotation operation. Is provided with a rotation restricting piece 33c. The cross-sectional circle of the cylindrical body 33a is formed into a cross-sectional circle having a curvature substantially equivalent to the concave surface of the outer side surface 32c of the pressing member 32 described above. The rotational axis of the cylindrical body 33a forms an eccentric shaft 33d that is offset from the center of the cylindrical body 33a. The pressure adjusting member 33 produced in this way is attached to the outside of the pressing member 32 fitted to the attachment member 20. As shown in FIG. 3, the mounting position is such that the eccentric shaft 33d is installed so as to be parallel to the central axis D of the grip insertion portion 31, and the pressing adjustment member 33 is rotated as shown in FIG. In addition, the pressing member 32 is attached at a position where the pressing member 32 can protrude into the grip insertion portion 31.

  As shown in FIG. 4, the grip fixing means 30 configured as described above inserts the grip 10 in a state where the pressing member 32 is biased outward (FIG. 5 a), and the groove 11 of the grip 10 is inserted. After turning to the pressing member 32 side, the pressing adjusting member 33 is rotated to move the pressing member 32 inward (FIG. 5b). Accordingly, the grip 10 is fixed by the pressing force of the pressing member 32, and the groove 10 of the grip 10 and the protrusion 32b of the pressing member 32 are fitted to each other and the grip 10 is reliably prevented from rotating. it can.

  On the other hand, as shown in FIG. 3, the support pole fixing means 40 includes a support pole insertion portion 41 into which the support pole 51 is inserted, and a support pole fixing member 42 that fixes the support pole.

  The support pole insertion portion 41 is formed of a long hole drilled in a direction perpendicular to the center axis D of the grip insertion portion 31. The long hole is formed in a hole having a long diameter in the direction of the central axis D, and is formed so that the width in the short direction gradually becomes narrower from one end to the other end.

  In this embodiment, the support pole fixing member 42 is formed of a bolt, and extends from one end to the other end, that is, from the wide end to the narrow end. And is attached to a screw hole formed at one end so as to enter the long hole.

  The support pole fixing means 40 thus manufactured is such that the support pole 51 is tightened with a support pole fixing member (bolt) 42 after the support pole 51 of the headrest 50 is inserted into the support pole insertion portion 41, so that the tip of the bolt causes the support pole 51 to move. The support pole 51 is fixed by pressing. In this way, the vehicle assist grip is attached to the support pole 51. At this time, the mounting pole 20 moves so that the supporting pole 51 moves from one end to the other end (from the wide side to the narrow side) in response to the fastening of the fixing member 42. To do. As a result, the support pole 51 moves in a direction in which the width becomes narrow according to the thickness of the pole. The movement is restricted and fixed at a position having a width equivalent to that of the support pole 51. Therefore, it becomes possible to fix the support poles 51 of various thicknesses.

  Similarly, after attaching the vehicle assist grip 100 to the other support pole 51, the vehicle seat assist grip 100 is attached to the vehicle seat as shown in FIG. A grip 10 is installed.
