DETAILED DESCRIPTION OF THE INVENTION
Reference will now be made in detail to a exemplary embodiments of the present invention an example of which is illustrated in the accompanying drawings and described below. While the invention will be described in conjunction with exemplary embodiments, it should be understood that the description is not intended to limit the invention to the exemplary embodiments. On the contrary, the invention is intended to cover not only the exemplary embodiment, but also various alternatives, modifications, equivalents and other embodiments, which may be included within the spirit and scope of the invention as defined by the appended claims. In particular, while exemplary embodiments are described in connection of a sunroof, it will be readily appreciated that the invention may be applied to other operable members that close openings in the vehicle cabin.
Referring to FIGS. 1 and 2, a sunroof switch assembly for a vehicle in accordance with an embodiment of the present invention includes a switch housing 100 and a push switch 200 mounted to the switch housing 100. A first tilting switch 300 is installed through a first hinge part 310 on one side of the push switch 200, and a second tilting switch 400 is installed through a second hinge part 410 on the other side of the push switch 200.
The switch housing 100 is arranged in the cabin of the vehicle and has contacts 110 for operating a sunroof. The plurality of switches thus provided are brought into electrical contact with respective contacts 110 to allow the sunroof to be operated.
In particular, the push switch 200, which is manipulated by being pushed, is located at the middle portion of the switch housing 100. The first tilting switch 300 and the second tilting switch 400, which are manipulated by being tilted, are respectively located on opposite sides of the push switch 200.
The push switch 200 has a connection terminal 220, which is brought into electrical connection with the contact 110 when it is pushed. The push switch 200 may comprise a closing switch for closing the opened sunroof when the connection terminal 220 is brought into electrical connection with the contact 110.
The push switch 200 projects a predetermined height from the switch housing 100. The predetermined height may be set to be less than the distance between the contact 110 and the connection 220 of the push switch 200. In this regard, the contact 110 and the connection terminal 220 may be separated from each other by a distance no less than 2 mm, and that the projecting height of the push switch 200 be set higher than the upper surfaces of the first hinge part 310 and the second hinge part 410 by about 1 mm or less.
Referring to FIG. 3, when the push switch 200 is inadvertently pushed by a large or rounded object 500, such as the palm of a hand or the elbow of a child, the sunroof may be prevented from closing as described below as to prevent a human body from being injured due to the closing of the sunroof.
The push switch 200 is located between the first tilting switch 300 and the second tilting switch 400 and is thus sandwiched between the first tilting switch 300 and the second tilting switch 400. The first tilting switch 300 is located on one side of the push switch 200 and has a connection terminal 320 which can be brought into electrical connection with the corresponding contact 110. The connection terminal 320 can be brought into electrical connection with the corresponding contact 110 of the switch housing 100 through the tilting operation of the first tilting switch 300. The fir tilting switch 300 may comprise a tilting switch for tilting the sunroof when the connection terminal 320 is brought into electrical connection with the contact 110.
The tilting operation of the first tilting switch 300 is implemented through the fist hinge part 310. The first hinge part 310 can comprise a rotation pin, both ends of which are supported by the switch housing 100. The first hinge part 310 is located adjacent to one side of the push switch 200 and serves as a rotation shaft for the tilting operation of the first tilting switch 300. Also, the first hinge part 310 is installed on the edge of the first tilting switch 300 adjacent to the push switch 200 and serves as a support shaft.
The second tilting switch 400 is located on the other side of the push switch 200 and has a connection terminal 420 which can be brought into electrical connection with the corresponding contact 110. The connection terminal 420 can be brought into electrical connection with the corresponding contact 110 of the switch housing 100 through the tilting operation of the second tilting switch 400. The second tilting switch 400 may comprise an opening switch for opening the sunroof when the connection terminal 420 is brought into electrical connection with the contact 110.
The tilting operation of the second tilting switch 400 is implemented through the second hinge part 410. The second hinge part 410 is located adjacent to the other side of the push switch 200 and serves as a rotation shaft for the tilting operation of the second tilting switch 400. To this end, the second hinge part 410 can comprise a rotation shaft both ends of which are supported by the switch housing 100.
The second hinge part 410 is installed on the edge of the second tilting switch 400 adjacent to the push switch 200. Thus, the second hinge part 410 can cooperate with the first hinge part 310 to serve as a support shaft which can restrain the amount that the push switch 200 is pushed when the push switch 200 is inadvertently pushed by a large or rounded object such as the palm of a hand or the elbow of a child.
As is apparent from the above description, the present invention provides advantages in that, since the hinge shafts of tilting switches prevent a closing switch from being inadvertently manipulated by the elbow of a child, it is possible to prevent the child from being injured by a closing sunroof.
Although a preferred embodiment of the present invention has been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
