Abstract

An armrest may include an armrest module, a sliding knob to be rotated by a manipulating force provided thereon, a hook knob facilitating rotation of the sliding knob to be converted into rotation for releasing console locking force for binding the armrest module, and a multi-link at which sloping angle rotation is generated by the rotation of the sliding knob and then converted into rotation for releasing slide locking force for binding sliding movement of the armrest module.

First claim

What is claimed is:

1. An armrest comprising:
an armrest module;
a sliding knob to be rotated by a manipulating force provided thereon;
a hook knob facilitating rotation of the sliding knob to be converted into rotation for releasing console locking force for binding the armrest module; and
a multi-link at which sloping angle rotation is generated by the rotation of the sliding knob and then converted into rotation for releasing slide locking force for binding sliding movement of the armrest module,
wherein the multi-link comprises:
a link bar having linear movement generated by the sloping angle rotation;
an interlock of which rotation is caused by the linear movement of the link bar and then converted into reverse rotation after pressing against the hook knob for the console locking force to be released at a position after the armrest module moves by a sliding stroke; and
a sliding hook which is rotated by the rotation of the interlock to release the slide locking force for binding sliding movement of the armrest module and generates the slide locking force at the position after the armrest module moves by a sliding stroke.

2. The armrest according to claim 1 , wherein the hook knob is positioned below a center of rotation of the sliding knob and the multi-link is positioned above the center of rotation of the sliding knob.

3. The armrest according to claim 1 , wherein spring elastic force is applied to each of the hook knob and the sliding knob, the spring elastic force being exerted as elastic restoring force when the hook knob and the sliding knob are returned to their initial states.

4. The armrest according to claim 3 , wherein a hook pushed end which is pushed by the rotation of the sliding knob is formed in the hook knob so as to extend toward one direction from a center of rotation of the sliding knob and a hook pushing end for pressing the hook pushed end is formed in the sliding knob to extend toward the one direction from the center of rotation of the sliding knob.

5. The armrest according to claim 1 , wherein the sloping angle rotation comprises sloping angle rotation of the sliding knob caused by a separation distance shared by the link bar and a center of rotation of the sliding knob and sloping angle rotation of the interlock caused by a separation distance shared by the link bar and a center of rotation of the interlock;
the linear movement is formed by both the sloping angle rotation of the sliding knob and the sloping angle rotation of the interlock;
the rotation of the interlock is generated by the separation distance shared by the link bar and the center of rotation of the interlock; and
the rotation of the sliding hook is generated through pushing by the rotation of the interlock applied from a position deviated from a center of rotation of the sliding hook.

6. The armrest according to claim 1 , wherein the link bar comprises a straight link bar body.

7. The armrest according to claim 1 , wherein the interlock comprises an interlock body having a center of rotation offset to one side,
the interlock body includes upper and lower pushing ends extended therefrom toward an opposite side of the center of rotation,
the upper pushing end rotates the sliding hook at a position before the armrest module moves by the sliding stroke, and
the lower pushing end presses against the hook knob to release the console locking force at a position after the armrest module moves by the sliding stroke and simultaneously converts the rotation of the interlock to the reverse rotation by reaction force of the hook knob.

8. The armrest according to claim 7 , wherein the upper pushing end and the lower pushing end form an open “C” shape in cross section.

9. The armrest according to claim 1 , wherein the sliding hook comprises a sliding hook body having a center of rotation offset to one side so that rotation of the sliding hook body is generated by the interlock and the slide locking force is released by the rotation of the sliding hook.

10. The armrest according to claim 9 , wherein spring elastic force is applied to the sliding hook body and the spring elastic force is exerted as elastic restoring force when the sliding hook is returned to its initial state.

11. The armrest according to claim 1 , wherein the multilink further comprises an interlock cover, the interlock cover allowing the link bar and the interlock and the sliding hook to be integrally assembled in a series arrangement.

12. The armrest according to claim 1 , wherein:
the rotation of the sliding knob, the rotation of the hook knob, and the rotation of the multi-link are generated about respective pins thereof; and
the pins are bound by E rings.

13. The armrest according to claim 1 , wherein the armrest module is coupled to the hinge module and the hinge module is formed as a hinge center of the armrest module when the armrest module is operated to be bent backward.

14. An armrest console comprising:
the armrest of the claim 1 , the armrest further comprising, a hinge module for forming a hinge center of the armrest module when the armrest module is operated to be bent backward; and
a console storage space exposed to the outside by bending the armrest backward.

15. The armrest console according to claim 14 , wherein the console storage space is formed at an armrest section and a shift lever section and a center fascia section are connected to the armrest section.

16. A vehicle comprising:
the armrest of the claim 1 , the armrest further comprising a hinge module for forming a hinge center of the armrest module when the armrest module is operated to be bent backward, and
an armrest console comprising an armrest section having a console storage space to be opened and closed by the armrest, a shift lever section connected to the armrest section, and a center fascia section connected to the shift lever section, and positioned between a driver seat and a passenger seat.
