Abstract

The invention relates to a method for operating a protective device (S) for a window opening (4) of a vehicle (1). According to the invention, a child (2) on a vehicle seat (3) in the region of the window opening (4) is detected, wherein when detected child (2) on the vehicle seat (3) one of the window opening (4) associated with power windows or limits movement of the window regulator and / or an extendable protective element covers the window opening (4).

Description

The invention relates to a method for operating a protective device for a window opening of a vehicle.

In general, the safety function of an anti-jamming device is known in the case of automatic window regulators in a vehicle. By means of the anti-trap protection prevents neither objects nor body parts are clamped during the closing operation of a window between a door frame and the window glass. In comparatively simple systems, the anti-pinch function is performed mechanically by means of a slip or friction clutch. Especially electronic windows with so-called comfort closure are designed with a relatively complex safety function. If a resistance is detected during a closing operation of the window pane, a movement of the window pane is automatically reversed so that the window pane opens again. For this purpose, a coupled to a drive unit electronics is provided, by means of which the resistance is detected.

The invention has for its object to provide a comparison with the prior art improved method for operating a protective device for a window opening of a vehicle.

The object is achieved by the features specified in claim 1.

Advantageous embodiments of the invention are the subject of the dependent claims.

A method for operating a protective device for a window opening of a vehicle according to the invention provides that a child is detected on a vehicle seat in the region of the window opening, wherein when detected child on the vehicle seat one of the window opening associated with windows, preferably locked in a closed position of the window opening or a movement of the window lifter is limited and / or an extendable protective element covers the window opening.

By applying the method, a driver of the vehicle is not forced to observe the child in order to at least reduce the risk of ejecting or throwing an object, in particular a toy, out of the vehicle.

By means of the method, the safety of all occupants of the vehicle and that of road users in the immediate vicinity of the vehicle is substantially increased.

Embodiments of the invention will be explained in more detail below with reference to a drawing.

It shows:

1 schematically a vehicle with a child in the rear area and open window.

In the only figure is a vehicle 1 pictured, being a child 2 on a vehicle seat 3 in the rear area of the vehicle 1 located and a window opening 4 partially open.

Through a comparatively large window opening 4 can be a relatively dangerous situation, especially due to items being used by the child 2 active or passive from the window opening 4 Thrown or thrown, arise. Is the window opening 4 opened and the child 2 Playing with objects, the concentration of a driver of the vehicle can 1 be compromised, thereby ensuring safety for all occupants of the vehicle 1 can be reduced.

To be able to exclude as far as possible that the child 2 an object, in particular a toy, from the window opening 4 casts or throws, a protective device S is provided.

By means of the protection device S is at commissioning of the vehicle 1 records whether a child 2 on the vehicle seat 3 located.

The detection of whether a child 2 on the vehicle seat 3 may be based on a detection of the use of a baby seat or a child seat. For example, the child becomes 2 itself, the baby seat or the child seat by means of a suitable sensor, for. B. in the form of at least one camera and / or at least one ultrasound, radar and / or laser-based detection unit and / or based on the use of a permanently installed child seat in the vehicle seat 3 recognized.

In addition, detected signals of an airbag key switch for a vehicle seat 3 associated side airbag for detecting the occupancy of the vehicle seat 3 be used by a child seat or a baby seat.

It is also conceivable that a arranged on a child seat transponder is detected by a corresponding detection unit, which is determined based on the detected transponder that a child seat on the vehicle seat 3 located.

Additionally or alternatively, by means of a connection between a child seat and standardized connection options in the vehicle 1 , such as Isofit or Isofix, or a different coupling between a child seat and the vehicle 1 , For example, wireless or wired, a child seat detected.

Again, additionally or alternatively, by means of electronic chips, by means of mobile devices and / or the like in or on the body of the child 2 For example, when sewn in clothing or tucked in a bag, it detects whether a child is 2 on the vehicle seat 3 located.

Furthermore, additionally or alternatively, an active child safety device can be located in the area of the vehicle seat 3 located vehicle door 5 be detected, whether a child 2 on the vehicle seat 3 located.

It is detected that a child 2 For example, a baby, on the vehicle seat 3 is, it is provided in one embodiment that, depending on a setting of the window opening 4 assigned window lifter locked or movement of the window can be limited, so that then the window opening 4 can only be opened to a limited extent.

In a further embodiment it is provided that when the child is detected 2 on the vehicle seat 3 automatically a sun blind as retractable protective element and / or a protective element of another kind, the window opening 4 covers.

By means of the protective element is the window opening 4 covered, thereby substantially avoiding objects, in particular toys, intentionally or unintentionally from the vehicle 1 to be thrown.

In addition, it can be provided in a further possible embodiment that is determined by means of detected signals in the vehicle interior arranged sensor units, in particular a camera, when an object in a hand of the child 2 is located and the hand of the window opening 4 approaches. If such a movement is detected with an object in the hand, the window opening 4 automatically closed by means of the power window, before the hand with the object the window opening 4 reached.

For this purpose, the sensor units can function ultrasound-based and / or radar-based, with object and position determination being carried out on the basis of detected signals. It is also conceivable that a wireless transmission between the object and the vehicle takes place, provided that the object is provided with a corresponding transmitting unit.

Preferably, the sensor unit is designed as a camera, which serves to determine whether a child 2 on the vehicle seat 3 and which is further intended to detect the movement of the hand or hands with an object.

Alternatively to the automatic closing of the window opening 4 the extendable protective element is activated to the window opening 4 cover.
