Abstract
This disclosure generally relates to a bushing arrangement for a headrest assembly of a seat in a vehicle. In one example of the present disclosure, the headrest assembly includes a rod configured to connect the headrest assembly to a seat back, and a head restraint. The head restraint includes a bushing configured to contact the rod and a spring configured to impart a force on an outer surface of the bushing. This arrangement allows a user to smoothly raise and lower the head restraint, and increases the stability of the head restraint relative to the rod.
Claims9
A headrest assembly, comprising:
- a rod configured to connect the headrest assembly to a seat back;
- and
- a head restraint including a bushing configured to contact the rod and a spring configured to impart a force on an outer surface of the bushing;
- wherein the bushing is integrally formed by a single piece of material;
- wherein the bushing includes an inner surface configured to contact the rod, and a slot extending from the inner surface to the outer surface;
- wherein the slot is bisected by a plane spaced-apart from a central axis of the rod;
- wherein:
- the bushing includes a first section and a second section spaced-apart from one another by the slot, and
- the spring is configured to urge the first and second sections toward one another;
- and
- wherein the spring is a separate piece from the bushing and applies the force to the bushing by applying an opposing force to a body of the head restraint that surroundingly holds the bushing in the headrest assembly.
A seat for a motor vehicle, comprising:
- a seat back;
- and
- a headrest assembly, comprising:
- a rod configured to connect the headrest assembly to the seat back;
- and
- a head restraint including a bushing configured to contact the rod and a spring configured to impart a force on an outer surface of the bushing;
- wherein the bushing is integrally formed by a single piece of material;
- wherein:
- the bushing includes an inner surface configured to contact the rod,
- the bushing includes a slot extending from the inner surface to the outer surface, and
- the slot is bisected by a plane spaced-apart from a central axis of the rod;
- wherein:
- the bushing includes a first section and a second section spaced-apart from one another by the slot, and
- the spring is configured to urge the first and second sections toward one another;
- and
- wherein the spring is a separate piece from the bushing and applies the force to the bushing by applying an opposing force to a body of the head restraint that surroundingly holds the bushing in the headrest assembly.
