Abstract

The present disclosure relates to a helmet, and the helmet according to an embodiment of the present disclosure includes a chin curtain ( 100 ) disposed at a chin guard ( 20 ) of a helmet body ( 10 ), wherein the chin curtain ( 100 ) rotates with respect to the chin guard ( 20 ).

Claims (35)

1 . A helmet comprising:

a chin curtain disposed at a chin guard of a helmet body,

wherein the chin curtain rotates with respect to the chin guard,

wherein the chin guard is rotatably coupled to the helmet body,

wherein when the chin guard rotates from a closed position to an open position,

the chin curtain rotates with respect to the chin guard,

and wherein a rotational direction in which the chin guard rotates with respect to the helmet body from the closed position to the open position while a rotational direction in which the chin curtain rotates with respect to the chin guard are the same.

2 . The helmet according to claim 1 , wherein the chin curtain includes:

a main body rotatably coupled to the chin guard around a rotation axis; and

a controller to rotate the main body in the downward direction when the chin guard rotates from the closed position to the open position.

3 . The helmet according to claim 2 , wherein the controller includes:

an elastic member to provide an elastic force to the main body to rotate the main body in the downward direction when the chin guard rotates from the closed position to the open position; and

a rotation control member to rotate the main body in an upward direction when the chin guard rotates to the closed position.

4 . The helmet according to claim 2 , wherein the main body is formed in an arc shape.

5 . The helmet according to claim 3 , wherein when the chin guard rotates to the closed position, the rotation control member comes into contact with an outer surface of the helmet body and rotates the main body in the upward direction.

6 . The helmet according to claim 3 , wherein the rotation control member is rotatably coupled to the chin guard around a first control axis, and when the chin guard rotates to the closed position, one side of the rotation control member comes into contact with an outer surface of the helmet body, and the other side of the rotation control member is rotatably coupled to the main body around a second control axis to rotate the main body.

7 . The helmet according to claim 6 , wherein the first control axis is disposed between one side and the other side of the rotation control member.

8 . The helmet according to claim 6 , wherein when the chin guard rotates to the closed position, one side of the rotation control member comes into contact with the outer surface of the helmet body and moves in the downward direction, and the other side of the rotation control member moves in the upward direction to rotate the main body in the upward direction.

9 . The helmet according to claim 3 , further comprising:

a stopper to limit a rotation angle of the rotation control member.

10 . The helmet according to claim 3 , wherein the main body is rotatably coupled to a center of the chin guard, and

wherein the rotation control member is rotatably coupled to a location away from the center of the chin guard, and is rotatably coupled to an end of the main body.

11 . A helmet comprising:

a chin curtain disposed at a chin guard of a helmet body, wherein the chin curtain rotates with respect to the chin guard, wherein the chin guard is rotatably coupled to the helmet body, wherein when the chin guard rotates from a closed position to an open position, the chin curtain rotates in a downward direction with respect to the chin guard, and wherein the chin curtain includes:

a main body rotatably coupled to the chin guard around a rotation axis; and

a controller to rotate the main body in the downward direction when the chin guard rotates from the closed position to the open position, wherein the controller includes:

an elastic member to provide an elastic force to the main body to rotate the main body in the downward direction when the chin guard rotates from the closed position to the open position; and

a rotation control member to rotate the main body in an upward direction when the chin guard rotates to the closed position.

12 . The helmet according to claim 11 , wherein when the chin guard rotates to the closed position, the rotation control member comes into contact with an outer surface of the helmet body and rotates the main body in the upward direction.

13 . The helmet according to claim 11 , wherein the rotation control member is rotatably coupled to the chin guard around a first control axis, and when the chin guard rotates to the closed position, one side of the rotation control member comes into contact with an outer surface of the helmet body, and the other side of the rotation control member is rotatably coupled to the main body around a second control axis to rotate the main body.

14 . The helmet according to claim 13 , wherein the first control axis is disposed between one side and the other side of the rotation control member.

15 . The helmet according to claim 13 , wherein when the chin guard rotates to the closed position, one side of the rotation control member comes into contact with the outer surface of the helmet body and moves in the downward direction, and the other side of the rotation control member moves in the upward direction to rotate the main body in the upward direction.

16 . The helmet according to claim 11 , further comprising a stopper to limit a rotation angle of the rotation control member.

17 . The helmet according to claim 11 , wherein the main body is formed in an arc shape.

18 . The helmet according to claim 11 , wherein the main body is rotatably coupled to a center of the chin guard, and wherein the rotation control member is rotatably coupled to a location away from the center of the chin guard, and is rotatably coupled to an end of the main body.
