## Abstract

A drive transmission system for a sheet-like structure movable in relation to a vehicle section, with at least one flexible drive cable which can transmit tensile and/or compressive forces, and with at least one stationary dimensionally stable conduit in which the drive cable is laid. The drive cable is guided in a slidably movable manner in a flexible plastic hose which is arranged in the conduit and which is held stationarily in relation to the conduit, the plastic hose having on the inside low sliding friction with respect to the drive cable.

## Claims

### Claim 1

A drive transmission system for a sheet-like structure movable in relation to a vehicle section, with at least one flexible drive cable which can transmit tensile and/or compressive forces, and with at least one stationary dimensionally stable conduit in which the drive cable is laid, wherein the drive cable is guided in a slidably movable manner in a flexible plastic hose which is arranged in the conduit and which is held stationarily in relation to the conduit, the plastic hose having on the inside low sliding friction with respect to the drive cable.

### Claim 2 (depends on 1)

The drive transmission system as claimed in claim 1, wherein the plastic hose extends at least largely over an entire length of the assigned drive cable.

### Claim 3 (depends on 1)

The drive transmission system as claimed in claim 1, wherein the plastic hose is provided partially with a longitudinal slot, through which a driver element of the drive cable projects laterally outward.

### Claim 4 (depends on 1)

The drive transmission system as claimed in claim 1, wherein the plastic hose is provided with supporting profilings which project laterally outward and which are formed in one piece on the plastic hose and cooperate positively with complementary profiling portions of the at least one conduit.

### Claim 5 (depends on 1)

The drive transmission system as claimed in claim 1, wherein the plastic hose is produced from polyoxymethylene as a homopolymer or copolymer.

### Claim 6 (depends on 1)

The drive transmission system as claimed in claim 1, wherein the flexible drive cable is designed as a tension- and pressure-transmitting pitch cable with an external coil ply for drive transmission, said pitch cable being sheathed over its entire length in a thin plastic layer.

### Claim 7 (depends on 6)

The drive transmission system as claimed in claim 6, wherein the plastic layer is composed of polyamide and has a layer thickness which corresponds to between 1% and 5% of a diameter of the pitch cable.

### Claim 8 (depends on 1)

The drive transmission system as claimed in claim 1, wherein the conduit has, distributed over its length, wall portions which are alternately open toward one side and toward the opposite side and are of channel-like shape and into which the plastic hose is introduced.

### Claim 9 (depends on 1)

The drive transmission system as claimed in claim 1, wherein fixing means, which fix the plastic hose positively or in a materially integral manner, are provided in the region of the conduit.

### Claim 10 (depends on 1)

A method for mounting a drive transmission system as claimed in claim 1, with at least one conduit shaped out of a frame part of the drive transmission system, wherein the plastic hose is introduced axially into the conduit and is fixed in the conduit, and wherein, thereafter, the drive cable is pushed into the plastic hose on the end face.

### Claim 11 (depends on 10)

The method as claimed in claim 10, wherein, after the drive cable has been pushed in, the driver element is fastened to the drive cable in the region of the longitudinal slot of the plastic hose.
