Sun shade apparatus

Abstract

The invention provides a sunshade device (1), which can spread a curtain (10) capable of shielding a window portion (2a) relative to a window portion (2a) of a vehicle door (23) in a range from a shielded state to an open state. , which has: a motor (71), a cable (6) configured to be pushed out or pulled back by the operation of the motor (71), and a connecting member connecting the cable (6) and the curtain (10) (90), the above-mentioned curtain (10) can be unfolded along with the above-mentioned push-out action or pull-back action of the above-mentioned cable (6), the above-mentioned connecting member (90) has a connection release mechanism, and the above-mentioned The connection release mechanism releases the connection between the cable (6) and the curtain (10) when a load greater than a predetermined value is applied in the push-out operation or the pull-in operation.

Description

technical field [0001] The present invention relates to a sunshade device mounted on a car door or the like. Background technique [0002] The motorized sunshade device on the door unfolds the curtain connected to the cable with the action of pushing out and pulling back the cable driven by the electric motor. In this way, the curtain is spread to cover the window portion of the vehicle door, which can prevent the temperature rise in the vehicle compartment and ensure the privacy of the vehicle compartment. For example, refer to Japanese Patent Application Laid-Open Publications No. 2003-182358 and No. 2005-96529. [0003] However, in such a sunshade device, since the curtain is unfolded by the driving of the motor, when a foreign object or the like is caught in the unfolding direction of the curtain, the direction of pushing out or pulling back the cable will be reversed. When an excessive load is applied in the direction of the cable, the cable, the curtain, or the conne...

Problems solved by technology

[0003] However, in such a sunshade device, since the curtain is unfolded by the driving of the motor, when a foreign object or the like is caught in the unfolding direction of the curtain, the direction of pushing out or pulling back the cable will be reversed. When an excessive load is applied in one direction, the cable, the curtain, or the connecting parts for connecting the cable and the curtain may deform, which may become a cause of failure.

[0004] In addition, in the past, guide grooves were required for deployment based on cables, but if, for example, a safety mechanism (stopping mechanism activated in an emergency) is installed on the movement stroke of the cable, it will increase the The large cross-sectional area of ​​the guide groove will narrow the driver's field of vision and make it difficult to confirm safety
