Motor vehicle having a fixed roof which can be opened and method of making same

An openable fixed roof for a motor vehicle, comprising:

• a front and a rear roof part being articulatedly connected to each other,
• a main link arrangement which operatively controls the roof parts to shift between a closing position and a storage position in a rear storage space,
• a fixed rear window being mounted pivotably on lateral roof pillars and being operatively rotationally driven relative to the roof pillars during opening and closing movement of the fixed roof, a pivot axis of the rear window running transversely in a central region of the rear window, the rear window, after reaching the closing positions of the fixed roof in use, being pressed via a rotational drive against a sealing seat interacting with the rear window, and
• a supporting arrangement which comprises at least one supporting element,
• wherein, when operatively pushed forward, the supporting element enables a rotational force to act on the rear window ensuring the sealing seat.

A method of making an openable fixed roof for a motor vehicle, comprising:

• providing a front and a rear roof part,
• connecting the roof parts to each other in an articulated manner,
• providing a main link arrangement to operatively control the roof parts to thereby operatively shift the roof parts between a closing position and a storage position in a rear storage space,
• pivotably mounting a fixed rear window of the roof parts on lateral roof pillars, a pivot axis of the rear window running in a central region of the rear window in a transverse direction of the vehicle, and the rear window being operatively driven in a rotational manner relative to the roof pillars during opening and closing movement of the fixed roof,
• connecting a rotational drive to the rear window to, after operatively reaching the closing position of the fixed roof, press the rear window against a sealing seat which operatively interacts with the rear window, and
• providing a supporting arrangement of at least one supporting element which, when operatively pushed forward, enables the rear window to operatively be acted upon by a rotational force ensuring the sealing seat of the rear window.

A method of operating an openable fixed roof of a motor vehicle, said roof having a front and a rear roof part which are connected to each other in an articulated manner, comprising:

• controlling the roof parts by way of a main link arrangement to shift between a closing position and a storage position in a rear storage space,
• pivoting a fixed rear window which is mounted pivotably on lateral roof pillars about a pivot axis of the rear window running in a central region of the rear window in a transverse direction of the vehicle, the rear window being driven in a rotational manner relative to the roof pillars during opening and closing movement of the fixed roof,
• pressing the rear window, after reaching the closing position of the fixed roof, via a rotational drive against a sealing seat interacting with the rear window, and
• pushing forward a supporting arrangement comprising at least one supporting element enabling the rear window to be acted upon by a rotational force to ensure the sealing seat of the rear window.
