## Abstract

A bidirectionally open sunroof structure includes rail assemblies installed at both sides of a roof panel, a front tilt lever connected to a front glass and the rail assembly and located at a front part of the front glass, a rear tilt lever connected to the front glass and the rail assembly and located at a rear part of the front glass, a front sled located on the front glass and driven by a driving motor to slidably reciprocate along the rail assemblies, and a rear sled located on a rear glass and driven by a driving motor to slidably reciprocate along the rail assemblies. The rail assembly includes a first guide rail configured to slidably move the front sled therealong, and a second guide rail located within the first guide rail and configured to slidably move the rear sled therealong.

## Claims

### Claim 1

A bidirectionally open sunroof structure comprising:
rail assemblies installed at both sides of a roof panel of a vehicle;
a front tilt lever connected to a front glass and the rail assembly and located at a front part of the front glass;
a rear tilt lever connected to the front glass and the rail assembly and located at a rear part of the front glass;
a front sled located on the front glass and driven by a driving motor to slidably reciprocate along the rail assemblies; and
a rear sled located on a rear glass and driven by a driving motor to slidably reciprocate along the rail assemblies,
wherein the rail assembly comprises:
a first guide rail configured to slidably move the front sled therealong; and
a second guide rail integrally formed with the first guide rail and configured to slidably move the rear sled therealong;
wherein the rear glass is configured to be inserted underneath the front glass along the rear sled, and to be moved in a front and rear direction of the vehicle.

### Claim 2 (depends on 1)

The bidirectionally open sunroof structure of claim 1, wherein, in order to move the front glass rearwards, the rear tilt lever and the front tilt lever raise the front glass.

### Claim 3 (depends on 1)

The bidirectionally open sunroof structure of claim 1, further comprising a lowering lever configured to lower the rear glass, when the rear glass is moved forwards.

### Claim 4 (depends on 1)

a first insert part configured to be inserted into at least one side surface of the first guide rail;
a first carriage configured to fix the front glass; and
a blocking part configured to prevent dust from being introduced into the bidirectionally open sunroof structure.

### Claim 5 (depends on 1)

The bidirectionally open sunroof structure of claim 1, wherein the rear sled comprises:
second insert parts configured to be inserted into the second guide rail; and
a second carriage configured to fix the rear glass.
