Definitions
- the present invention relates to a hinge device whose rotational torque changes depending on a rotational angle, and in particular, an optimal hinge for attaching an overhead liquid crystal display device for viewing a rear seat occupant so as to be openable and closable.
- the present invention relates to a device and an opening / closing mechanism using the hinge device.
- a vehicle rear seat occupant display includes, for example, a base member provided on the ceiling of a car, a display device provided on a lid, and the lid provided with the display device is opened and closed at an easy-to-view angle. It is connected with a hinge device so that it can.
- a hinge device for example, a relatively low rotational torque (resistance torque) is applied at the start position, a relatively high rotational torque is applied at the intermediate position, and a maximum rotational torque that can maintain a stopped state is applied at the normal position. It is preferable that it is comprised.
- an elastic member provided with a fixing member provided with a recess and a hole in the rotation direction and an arm portion extending from the rotation center portion to the outer peripheral side, and provided with a protrusion at the free end of the arm portion.
- a braking member formed of a material and an elastic member for pressing the braking member against the fixing member, and a region where the protrusion of the braking member slides on the fixing member is subjected to high torque and protrudes at the circumferential recess. It is known that a low torque is applied to a region where the sliding contact is avoided, and a maximum torque is applied when the protrusion falls into the hole and gets on (see, for example, Patent Document 1).
- Patent Document 1 Japanese Patent Laid-Open No. 2003-56547
- the conventional position (angle) for viewing is the position where the protrusion of the braking member fits into the hole of the fixing member, but the hole of this fixing member is provided Because the number is limited, there is a problem that the viewing angle is limited, and it may be difficult to see depending on the line of sight of the passenger and the sitting height.
- the conventional hinge device is a low-torque region where the protrusion of the braking member is avoided by the concave portion of the fixing member during the approximately 30 ° from the start (during T1). Therefore, the fall (opening) of the hinge device due to its own weight suddenly drops (opens) to approximately 30 ° from the start, and there is a problem of degrading the quality. If the torque during this period is increased to improve, there was a problem that even if the lock was released, it could not fall by its own weight.
- the free stop area which is the area where the conventional hinge device is actuated by hand, is the area where the protrusion of the braking member slides against the plane of the fixed member, so the generated torque is always constant, and the operation by hand. There was a problem with a heavy feeling and operation.
- the present invention has been made in view of the above points, and an object of the present invention is to allow the viewing angle of the display device to be set at an arbitrary position so that all passengers can view at an optimum angle.

- the protrusion is characterized in that the protrusion is slidably in contact with the protrusion (including the tapered portion), and the protrusion has a flat portion at least at one end continuous with the flat portion.
- the braking member is pressed against the bracket by the leaf spring member. Therefore, when the protrusion of the braking member is located in the groove of the bracket, the sliding contact of the protrusion of the braking member is the groove. This is a low torque area to be avoided.
- the protrusion of the braking member is located at the tapered portion of the concave groove of the bracket, the torque gradually increases, and the position where the protrusion of the braking member slides on the bracket is high. This is the torque area. Therefore, for example, if the position where the display device is housed in the ceiling of the vehicle is set as the position of the groove of the bracket when the protrusion of the braking member is the position of the groove of the bracket, the display device is locked (locked).
- the display device When is released, the display device begins to drop (open) by its own weight.
- the protrusion of the braking member is applied to the taper portion of the concave groove of the bracket, the torque gradually increases, so that the speed of dropping (opening) of the display device gradually decreases and finally stops.

If one of the hinge devices is operated and the spring force of the leaf spring member is increased in the free stop region, and the other hinge device is operated, the movement can be moderated in the area where the weight falls, and in the free stop region. The stop can be ensured with high torque.
