Abstract

A hatch in a fixed roof surface of a motor vehicle with a frame (1) which is located in the roof cutout in the roof surface, with a cover (2) which can be opened and closed relative to the frame (1) via a raising mechanism, and with an actuating mechanism for the raising mechanism, the raising mechanism having a first pair of toggle joints (3 and 4) which are supported on the frame (1) to raise one edge of the cover (2) and a second pair of toggle joints (5 and 6) which are supported on the frame (1) to raise the opposite edge of the cover (2), and the actuating mechanism having a transmission mechanism (24) which can be moved along the frame (1), which is guided on the frame (1), and to which actuating elements (28, 29 and 30, 28′, 29′, 30′) are attached for simultaneous actuation of the toggle joints of a respective one of the first and second pairs of toggle joints (3, 4 and 5, 6).

Dependent claims

Hatch in a fixed roof surface of a motor vehicle comprising:

a frame which is located in a roof cut out opening in the fixed roof surface;
a cover which can be opened and closed relative to the frame;
a raising mechanism for raising and lowering said cover;
and
an actuating mechanism for actuating the raising mechanism;
wherein the raising mechanism has a first pair of toggle joints which are supported on the frame and are connected to a first edge area of the cover and a second pair toggle joints which are supported on the frame and are connected to a second edge of the cover which is at an opposite side of the cover from said first edge area;
wherein the actuating mechanism has a transmission which is movable along the frame in a guided manner and to which actuating elements are attached at a series of positions, the actuating elements at each position of the series simultaneously actuating the toggle joints of a respective one of said first and second pairs of toggle joints in a respective one of raising and lowering motions, one of the actuating elements engaging one of said first and second toggle joints for producing a tilting up of the cover at one edge into an open position in a first direction of movement of the transmission, another of said actuating elements engaging the other of said first and second toggle joints in a manner causing an opposite edge of the cover to be swung up into an open position in said first direction of movement of the transmission and produce a lowering motion of the respective edge in an opposite direction of movement of the transmission.
