Abstract
A plurality of pressing portions 38 protrude inward in a radial direction from an inner peripheral surface of a tubular main body portion 35 (part of a tube body) and are each fixed at both ends thereof in an up-down direction to the main body portion 35. Since the plurality of pressing portions 38 are aligned in the up-down direction, a stay 22 or 23 can be inhibited from oscillating with a contact portion between one pressing portion 38 and the stay 22 or 23 as a fulcrum. As a result, rattling of the stay 22 or 23 relative to a headrest holder 30 or 31 can be suppressed.
Claims8
A headrest holder to be attached to an upper frame of a back frame of a passenger seat, the headrest holder comprising:
- a tube body into which a stay of a headrest capable of supporting a head of a seated person from back is inserted from an upper end thereof;
- and
- a plurality of pressing portions protruding inward in a radial direction from an inner peripheral surface of the tube body so as to be pressed against the stay, and formed so as to be aligned in an up-down direction, wherein
- each of the pressing portions is fixed at both ends thereof in the up-down direction to the tube body;
- wherein the tube body includes:
- a tubular upper end portion forming an upper end side of the tube body, and
- a tubular main body portion extending downward from the upper end portion,
- a projection portion protrudes inward in the radial direction from a front side of an inner peripheral surface of the upper end portion, and
- the pressing portions protrude inward in the radial direction from a back side of an inner peripheral surface of the main body portion;
- wherein
- the headrest holder has a locking mechanism for fixing a vertical position of the stay by engaging a groove provided on an outer peripheral surface of the stay, or does not have the locking mechanism, and
- the projection portion is provided separately from the locking mechanism when the headrest holder has the locking mechanism.
A headrest holder to be attached to an upper frame of a back frame of a passenger seat, the headrest holder comprising:
- a tube body into which a stay of a headrest capable of supporting a head of a seated person from back is inserted from an upper end thereof;
- and a plurality of pressing portions protruding inward in a radial direction from an inner peripheral surface of the tube body so as to be pressed against the stay, and formed so as to be aligned in an up-down direction, wherein each of the pressing portions is fixed at both ends thereof in the up-down direction to the tube body;
- further comprising a pair of projection portions protruding inward in the radial direction from the inner peripheral surface of the tube body,
- wherein the pair of projection portions are arranged symmetrically in a circumferential direction at positions opposing the pressing portions when viewed in an axis direction of the tube body.
