Abstract

A vehicle cargo compartment, comprising a housing receivable in a vehicle, and at least one latch mounted to the housing for locking a cargo unit in a fixed position. The latch comprises a latch housing mounted to the housing, and at least a first latch claw moveably mounted to the latch housing moveable between a latched and an unlatched position. A latch sensor system comprises a position sensor and a target, the position sensor adapted to detect and generate a latch signal when the target is in the predetermined position. The vehicle cargo compartment can be monitored easily and reliably when the first latch claw is in the latched position due to the position sensor and the target being arranged and adapted such that the predetermined position of the target is detected and the latch signal is generated, when the first latch claw is in the latched position.

First claim

The invention claimed is:

1. A vehicle cargo compartment, comprising:
a compartment housing adapted for being received in a vehicle,
at least one latch device mounted to said compartment housing and adapted for locking a cargo unit received in said vehicle cargo compartment, in a fixed position with respect to said compartment housing,
said latch device comprising a latch housing mounted to said compartment housing, and at least a first latch claw moveably mounted to said latch housing,
said first latch claw being moveable between a latched position, where the first latch claw is adapted to engage a corresponding engagement section on a cargo unit received in the vehicle cargo compartment, and an unlatched position, where the first latch claw is adapted to disengage from said engagement section,
a latch sensor system comprising a position sensor and a target element, said position sensor being adapted for detecting a predetermined position of the target element and generating a latch signal when the target element is in said predetermined position,
one of the position sensor and the target element being mounted to the first latch claw and the other one of the position sensor and the target element being mounted to the latch housing, to the compartment housing, or to a second latch claw moveably mounted to the latch housing, and
the position sensor and the target element being arranged and adapted in such a manner that the predetermined position of the target element is detected and the latch signal is generated, when the first latch claw is in the latched position.

2. A vehicle cargo compartment according to claim 1 , wherein the position sensor is arranged on the compartment housing and the target element is arranged on the first latch claw.

3. A vehicle cargo compartment according to claim 1 , wherein the position sensor is arranged on the latch housing and the target element is arranged on the first latch claw.

4. A vehicle cargo compartment according to claim 1 , wherein the position sensor is arranged on the first latch claw and the target element is arranged on the second latch claw.

5. A vehicle cargo compartment according to claim 1 , wherein the compartment housing comprises a housing floor and two opposite housing side walls surrounding a compartment interior space,
wherein the housing floor has an inner surface facing the compartment interior space,
wherein on said inner surface of the housing floor a roller track is provided extending in parallel to said housing side walls, and
wherein the roller track comprises a track housing and a plurality of rollers rotatably mounted to said track housing, each roller having an axis of rotation extending perpendicularly with respect to the direction of extension of the roller track, and being adapted to engage a lower surface of a cargo unit received in said vehicle cargo compartment.

6. A vehicle cargo compartment according to claim 5 , wherein the latch device is mounted to the track housing of the roller track between two subsequent rollers in such a manner that the first latch claw,
when in the latched position, projects up over the level in which the rollers are adapted to engage the lower surface of a cargo unit, and
when in the unlatched position, is retracted under the level in which the rollers are adapted to engage the lower surface of a cargo unit.

7. A vehicle cargo compartment according to claim 5 , wherein the first latch claw comprises a first claw arm and a first claw head connected to said first claw arm and adapted to engage a corresponding engagement section on a cargo unit received in the vehicle cargo compartment,
wherein the first claw arm is mounted to the latch housing pivotally by means of a first hinge, an axis of rotation of said first hinge being parallel to the axes of rotation of the rollers in the roller track,
wherein the first claw arm comprises an inner first arm section extending between the first hinge and the first claw head, and an outer first arm section extending away from the first hinge on that side of the first hinge opposite from the inner first arm section.

8. A vehicle cargo compartment according to claim 5 , wherein the position sensor is arranged on the compartment housing and the target element is arranged on the first latch claw, wherein the position sensor is mounted to the track housing underneath the latch device.

9. A vehicle cargo compartment according to claim 8 , wherein the first latch claw comprises a first claw arm and a first claw head connected to said first claw arm and adapted to engage a corresponding engagement section on a cargo unit received in the vehicle cargo compartment,
wherein the first claw arm is mounted to the latch housing pivotally by means of a first hinge, an axis of rotation of said first hinge being parallel to the axes of rotation of the rollers in the roller track,
wherein the first claw arm comprises an inner first arm section extending between the first hinge and the first claw head, and an outer first arm section extending away from the first hinge on that side of the first hinge opposite from the inner first arm section,
wherein the position sensor is directed upwards away from the housing floor, and
wherein the target element is mounted to the inner first arm section of the first claw arm.

10. A vehicle cargo compartment according to claim 8 , wherein the first latch claw comprises a first claw arm and a first claw head connected to said first claw arm and adapted to engage a corresponding engagement section on a cargo unit received in the vehicle cargo compartment,
wherein the first claw arm is mounted to the latch housing pivotally by means of a first hinge, an axis of rotation of said first hinge being parallel to the axes of rotation of the rollers in the roller track,
wherein the first claw arm comprises an inner first arm section extending between the first hinge and the first claw head, and an outer first arm section extending away from the first hinge on that side of the first hinge opposite from the inner first arm section,
wherein the position sensor is directed in parallel to the axis of rotation of the first hinge, and
wherein the target element is mounted to the outer first arm section of the first claw arm.

11. A vehicle cargo compartment according to claim 7 ,
wherein the position sensor is arranged on the first latch claw and the target element is arranged on the second latch claw,
wherein the second latch claw comprises a second claw arm and a second claw head connected to said second claw arm and adapted to engage a corresponding engagement section on a cargo unit received in the vehicle cargo compartment,
wherein the second claw arm is mounted to the latch housing pivotally by means of a second hinge, an axis of rotation of said second hinge being parallel to the axis of rotation of the first hinge, and
wherein the second claw arm comprises an inner second arm section extending between the second hinge and the second claw head, and an outer second arm section extending away from the second hinge on that side of the second hinge opposite from the inner second arm section.

12. A vehicle cargo compartment according to claim 11 ,
wherein the first latch claw and the second latch claw are arranged such that they pivot in reverse directions of rotation, when moved between the latched position and the unlatched position,
wherein the first claw head and the second claw head are arranged opposite one another, when they are in the latched position, and
wherein the position sensor is mounted to the first claw head and the target element is mounted to the second claw head, such that the position sens
