Abstract
A seat head rest for a vehicle includes a stay member for being mounted on a seat back, a rigid frame pivotably mounted on the stay member and a pad member fixed to the rigid frame forming a head rest body with the rigid frame, wherein the rigid frame further includes a frictional portion which is integrally formed with the rigid frame and which frictionally engages the stay member.
Claims12
A seat head rest for a vehicle, comprising:
- a stay member for mounting on a seat back and including a pair of vertical rod portions and a horizontal rod portion connected to the vertical rod portions;
- a frame pivotably mounted on the stay member and including at least a wall portion engageable with the stay member and a friction portion extending from a lower portion of the frame and being curled so as to be wound around the horizontal portion of the stay, the frame being formed with a plate member which is untarily formed with the wall portion and the friction portion;
- and
- a pad member fixed to the frame and forming a head rest body with the frame.

A seat head rest for a vehicle comprising:
- a stay member, including pair of horizontal rod portion and a pair of vertical rod portions, for mounting on a seat back,
- a frame being a plate member with an integral wall, said wall having a body portion with a pair of side portions, and a first extension portion and a second extension portion, the first extension portion extending from the pair of side portions, the second extension portion extending from a lower portion of the body portion and including a friction portion curled around the horizontal rod portion frictionally engaging the stay member and pivotably mounted on the stay member, the second extension portion being clamped to the body portion to generate frictional force between the friction portion and the horizontal rod portion, at least one of the second extension portions and the body portion including a deformable projection for adjusting the frictional force between the friction portion and the horizontal rod portion, and
- a pad member fixed to the frame and forming a head rest body with the frame.

A seat head rest for a vehicle, comprising:
- a stay member, including a pair of horizontal rod portions, for mounting on a seat back;
- a frame being a plate member having a body portion and an extension portion extending from the body portion;
- a pad member fixed to the frame and forming a head rest body with the frame,
- said extension portion including an integral friction portion having an elastic fulcrum curled around each of the horizontal rod portions to pivotably and frictionally engage the stay member, the extension portion including a connecting portion, spaced from each of the respective elastic fulcrums in a direction forward of the headrest body, clamping the extension portion to the body portion for generating frictional forces between the friction portions and the horizontal rod portions.
