Abstract

The objective of the present invention is to provide a wearable video display device ( 10 ) with which the fitting comfort for a user (U) can be improved while suppressing shifting of a display unit ( 11 ). The wearable video display device comprises: the display unit ( 11 ); a left frame ( 17 ) and a right frame ( 18 ) which extend in a rearward direction from the display unit and are provided independently of one another; a forehead support portion ( 26 ) which accepts a supporting force from a supra-orbital margin of the user's forehead; and a nose support portion ( 27 ) that accepts a supporting force from the user's nose. Rear regions of the left frame and the right frame serve as occipital support portions ( 23, 24 ) that accept a supporting force from the back of the user's head. The total weight of the wearable video display device is set to 300 gf or less, and the total weight is supported by the forehead support portion, the nose support portion, and the occipital support portions.

First claim

1 . A wearable video display device which is worn on the head of a user and which comprises
a display unit provided with a display element and an eyepiece optical system accommodated in a housing, a left frame and a right frame which extend in a rearward direction from the display unit and are provided independently of one another, a forehead support portion which accepts a supporting force from a supra-orbital margin of the user's forehead, and a nose support portion which accepts a supporting force from the user's nose, wherein: rear regions of the left frame and the right frame serve as occipital support portions that accept a supporting force from the back of the user's head; and a total weight of the wearable video display device is set to 300 gf or less, and the total weight is supported by the forehead support portion, the nose support portion, and the occipital support portions.

2 . The wearable video display device as claimed in claim 1 , wherein the forehead support portion and the occipital support portions apply a pinching force to the head of the user from front and rear directions, and the nose support portion applies a force due to a portion of the total weight onto the nose of the user.

3 . The wearable video display device as claimed in claim 1 or claim 2 , wherein the occipital support portions are configured by forming rear regions of the left frame and the right frame with a curved shape when viewed from above, and
a part of the forehead support portion that comes into contact with the forehead of the user is formed with a curved shape when viewed from above.

4 . The wearable video display device as claimed in any one of claims 1 to 3 , wherein the forehead support portion is provided divided to the left and right, sandwiching the nose support portion, when viewed from above.

5 . The wearable video display device as claimed in any one of claims 1 to 4 , wherein a front end side of the left frame and a front end side of the right frame are connected to a front frame, and the front frame is fitted to the display unit.
