Abstract

A steering wheel for a vehicle may include: a damper part installed in a connection hole of a horn plate, and formed of an elastic material; a horn bolt part fixed to a hub part through the damper part, and configured to guide movement of the horn plate; a damper housing located between the damper part and the horn bolt part, and moved with the damper part; and a horn spring configured to support the damper housing, and having elasticity.

First claim

What is claimed is:

1. A steering wheel for a vehicle, comprising:
a damper part installed in a connection hole of a horn plate, and formed of an elastic material;
a horn bolt part fixed to a hub part through the damper part, and configured to guide movement of the horn plate;
a damper housing located between the damper part and the horn bolt part, and moved with the damper part; and
a horn spring configured to support the damper housing, and having elasticity,
wherein the horn bolt part comprises:
a head member located on a top of the horn plate,
a bolt body extended from the head member through an inside of the damper housing, and
a fastening body extended from the bolt body and fixed to the hub part,

wherein the damper housing comprises:
a first damper housing extended from the top of the horn plate to a bottom of the damper part, and
a second damper housing located under the damper part, fastened to the first damper housing, and supported by the horn spring,

wherein the first damper housing comprises:
a housing head located between the damper part and the head member,
a first housing body extended from the housing head, and located between the damper part and the bolt body, and
a fixing body extended from the first housing body, and having a screw thread formed on an outside thereof such that the second damper housing is fastened to the screw thread.

2. The steering wheel of claim 1 , wherein the damper part comprises:
an inner member installed in a ring shape while abutting on the inside of the damper housing;
an outer member located outside the inner member, and installed in a shape to cover the horn plate; and
a connection member configured to connect the inner member and the outer member.

3. The steering wheel of claim 1 , wherein the top of the housing head supports the head member, and the bottom of the housing head abuts on the damper part.

4. The steering wheel of claim 1 , wherein the second damper housing comprises:
a second housing body fastened to the outside of the fixing body; and
a support member extended outward from the second housing body, and supported by the horn spring.

5. The steering wheel of claim 4 , wherein the first damper housing further comprises a release prevention protrusion protruding from a bottom surface of the fixing body, facing the second housing body, and inserted and locked into the second housing body.

6. A steering wheel for a vehicle, comprising:
a damper part installed in a connection hole of a horn plate, and form of an elastic material;
a horn bolt part fixed to a hub part through the damper part, and configured to guide movement of the horn plate;
a first damper housing located between the damper part and the horn bolt part, and extended from a top of the horn plate to a bottom of the damper part;
a second damper housing located under the damper part, fastened to the first damper housing, and supported by a horn spring; and
the horn spring configured to support the second damper housing, and having elasticity,
wherein the first damper housing comprises:
a housing head located between the damper part and a head member of the horn bolt part,
a first housing body extended from the housing head, and located between the damper part and the horn bolt part,
a fixing body extended from the first housing body, and having a screw thread formed on an outside thereof such that the second damper housing is fastened to the screw thread, and
a release prevention protrusion protruding from a bottom surface of the fixing body, and inserted and locked into the second damper housing.

7. A steering wheel for a vehicle, comprising:
a damper part installed in a connection hole of a horn plate, and formed of an elastic material;
a horn bolt part fixed to a hub part through the damper part, and configured to guide movement of the horn plate;
a damper housing located between the damper part and the horn bolt part, and moved with the damper part; and
a contact plate part installed between the damper housing and the damper part.

8. The steering wheel of claim 7 , wherein the damper part comprises:
an inner member installed in a ring shape while abutting on the inside of the damper housing;
an outer member located outside the inner member, and installed in a shape to cover the horn plate; and
a connection member configured to connect the inner member and the outer member.

9. The steering wheel of claim 8 , wherein the damper part further comprises a fixing protrusion extended from the outer member and inserted and locked into a fixing hole of the horn plate.

10. The steering wheel of claim 7 , wherein the horn bolt part comprises:
a head member located on the top of the horn plate;
a bolt body extended from the head member through the inside of the damper housing; and
a fastening body extended from the bolt body and fixed to the hub part.

11. The steering wheel of claim 7 , wherein the damper housing comprises:
a first damper housing extended from the top of the horn plate to the bottom of the damper part; and
a second damper housing located under the damper part, fastened to the first damper housing, and supported by a horn spring.

12. A steering wheel for a vehicle, comprising:
a damper part installed in a connection hole of a horn plate, and formed of an elastic material;
a horn bolt part fixed to a hub part through the damper part, and configured to guide movement of the horn plate;
a damper housing located between the damper part and the horn bolt part, and moved with the damper part;
a first contact plate part comprising a first inner protrusion disposed between the damper part and the damper housing; and
a second contact plate part comprising a second inner protrusion disposed between the damper part and the damper housing.

13. The steering wheel of claim 12 , wherein the damper part comprises:
a damper body installed in such a shape that the inside thereof abuts on the damper housing and the outside thereof covers the horn plate; and
a fixing protrusion extended from the damper body, and inserted and locked into a fixing hole of the horn plate, such that the first and second contact plate parts abut on the outside thereof.

14. A steering wheel for a vehicle, comprising:
a damper part installed in a connection hole of a horn plate, and formed of an elastic material;
a horn bolt part fixed to a hub part through the damper part, and configured to guide movement of the horn plate;
a first damper housing located between the damper part and the horn bolt part, and extended from the top of the horn plate to the bottom of the damper part;
a second damper housing located under the damper part, fastened to the first damper housing, and supported by a horn spring;
