Abstract

An arrangement and method for remotely unlocking and raising a closure member such as the hatchback (12) of a motor vehicle (10) is described. Firstly, a signal (24) is sent to unlock and unlatch the vehicle hatchback (12). The unlatched hatchback (12) is automatically raised by an initial amount sufficient to allow gas springs (18) to continue the raising operation. The gas springs (18) may incorporate a device to prevent the hatchback being fully raised.

Description

OPENING ARRANGEMENTS AND METHODS FOR CLOSURE MEMBERS The invention relates to opening arrangements and methods for closure members. More particularly, though not exclusively, it relates to opening arrangements for opening doors and other closure members such as lids for engine and luggage compartments and hatchbacks.
According to the invention there is provided a closure opening method, comprising the steps of emitting a signal from a remote location; detecting the signal and causing an unlatching mechanism to be operated; and opening the closure to an initial extent sufficient for a controlled opening mechanism to become operative and to open the closure to a predetermined greater extent.
According to the invention there is further provided a remotely operable closure opening arrangement, comprising a releasable latching mechanism for latching the closure in the closed position, a controlled opening mechanism operative to open the closure from an initial partially open position, signal emitting means for emitting an opening signal from a remote location, detecting means for detecting the signal and releasing the latching mechanism, and initial opening means responsive to release of the latching mechanism to open the closure to the initial position whereafter the controlled opening mechanism opens the closure to a predetermined extent.
Hatchback and luggage compartment opening arrangements, embodying the invention, for use in motor vehicles will now be described, by way of example only, with reference to the accompanying diagrammatic drawings in which: Figure 1 is a side view of the rear of a motor vehicle showing the hatchback in a closed position; Figure 2 is a side view of the rear of a motor vehicle showing the hatchback in a fully raised position; and Figure 3 is a schematic block diagram of the controls of an embodiment of the invention.
The motor vehicle 10 has a hatchback 12 pivotally attached to the body of the vehicle 14 by hinges 16. The hatchback 12 is retained in the closed position by means of a latch and a locking mechanism 20. The latch and locking mechanism 20 can be operated remotely by a portable key device 22 (see Figure 3).
Gas springs 18 (Figure 2, which shows only one of the gas springs) are provided for lifting the hatchback 12 and retaining it in the open position.
To open the hatchback, in accordance with the invention, the operator presses the appropriate button on the separate key device. A suitable signal (such an an infra-red or radio signal) is accordingly emitted by the key device 22 which in turn is detected by a detector 26. The detector 26 emits a signal on a line 30 that activates a component 32 to unlock the latch mechanism 20.
A spring 34 or any other suitable means then raises the unlatched hatchback 12 slightly and to a level where the gas springs 18 can become operative and raise the hatchback.
The control unit 32 can be part of the central door locking system. However, preferably it can cause the hatchback to open independently of the other vehicle doors.
Additionally, the key device 22 may have other functions such as unlocking the central door locking or arming the vehicle alarm and need not be solely for raising the hatchback.
Furthermore, it will be appreciated that the vehicle need not be a hatchback motor vehicle, and the vehicle part to be opened need not be the hatchback, but could for example be another closure member which is opened by a gas spring or similar means when unlatched, such as the lid of a luggage compartment.
In a modified embodiment of the invention, the gas springs 18 allow the hatchback 12 to be raised only to a certain predetermined intermediate level less than the fully open position. This reduces the risk that the hatchback 12 will be damaged by contacting a low roof or other obstruction. The hatchback can thereafter be caused to rise to the fully open position if desired, by manual force or by further unlatching action.

Claims (16)

1. A closure opening method, comprising the steps of emitting a signal from a remote location; detecting the signal and causing an unlatching mechanism to be operated; and opening the closure to an initial extent sufficient for a controlled opening mechanism to become operative and to open the closure to a predetermined greater extent.
2. A method according to claim 1, in which the predetermined extent to which the closure is opened by the controlled opening mechanism is less than the fullest extent of opening.
3. A method according to claim 2, in which the closure can be opened to the fullest extent from the predetermined extent.
4. A remotely operable closure opening arrangement, comprising a releasable latching mechanism for latching the closure in the closed position, a controlled opening mechanism operative to open the closure from an initial partially open position, signal emitting means for emitting an opening signal from a remote location, detecting means for detecting the signal and releasing the latching mechanism, and initial opening means responsive to release of the latching mechanism to open the closure to the initial position whereafter the controlled opening mechanism opens the closure to a predetermined extent.
5. An arrangement according to claim 4, in which the predetermined extent to which the closure is opened by the gas spring is less than the fullest extent of opening.
6. An arrangement according to claim 5, in which the closure can be opened to the fullest extent from the predetermined extent.
7. An arrangement or method according to any preceding claim in which the signal is an infra-red signal.
8. An arrangement or method according to any preceding claim in which the signal is a radio signal.
9. An arrangement or method according to any preceding claim in which the unlatching mechanism is part of a central door locking system in a motor vehicle.
10. An arrangement or method according to any preceding claim in which the closure is opened to the initial extent by a spring mechanism.
11. An arrangement or method according to any preceding claim in which the closure is opened to the initial extent by an electric actuator.
12. An arrangement or method according to any preceding claim in which the controlled opening mechanism is a gas spring.
13. An arrangement or method according to any preceding claim, in which the closure is an openable motor vehicle door or lid.
14. An arrangement according to claim 13, in which the door is a hatchback.
15. A closure opening method substantially as herein described with reference to Figures 1 to 3.
16. A remotely operable closure opening arrangement substantially as herein described with reference to Figures 1 to 3.
