Description

2340178 MOTOR VFHICLF DOOR ASSEMBLY The invention relates to a motor
vehicle door assembly, and in particular to a hinged motor vehicle door assembly.
A vehicle door can often be damaged on opening by being swung into contact with another obstruction, for example a wall or lamppost. This may be due to carelessness on the part of the user, or ignorance, because the obstruction, such as a bollard cannot be seen, or easily seen, from within the vehicle. In any event, the vehicle door becomes damaged by being chipped, scratched, dented or otherwise. In order to return the vehicle to an "as new" condition, repair will need to be effected to the vehicle door. This is both time-consuming and expensive.
The present invention has as an advantage that the likelihood of damaging a motor vehicle door assembly in this way is eliminated or substantially reduced.
According to the invention there is provided a user operated motor vehicle door assembly comprises a door pivotally mounted on a body of a vehicle to move through a defined path and a door check means to limit opening of the door and to resist movement of the door, characterised in that the assembly ftirther comprises sensor means to detect the presence of an obstruction in the path of the door and in that the door check means comprises a stay connected at a first end to one of the body and the door and having a second end slidably connected to the other of the body and the door and stop means to prevent a further movement of the door by a user, the stop means being actuated by the sensor detecting an obstruction in the path of the door.
Preferably, the sensor is a non-contact sensor.
Preferably the stop means comprises a hydraulic or pneumatic cylinder. Alternatively, the stop means comprises an electromechanical device such as a releasable clamp or a selectable clutch.
Preferably, means are provided to disable the stop means in the event of a crash.
The sensor is preferably mounted on the vehicle body beneath the door. Alternatively, the sensor is mounted in the door, for example on a door handle. a wing mirror or a window frame.
The invention will now be described by way of example only with reference to the accompanying drawings, in which:
Figure 1 shows a perspective view of a motor vehicle door assembly according to the present invention with the door open and an interior panel of the door removed: and Figure 2 shows a perspective view of a motor vehicle for use with the vehicle door assembly of the present invention.
Refer-ring first to Figure 1, there is shown a door assembly 10 comprising a door 12 pivotally connected to a door frame forming part of a body of a motor vehicle by hinges 16.
The door pivots about a generally vertical axis defted by the hinge connections between the door 12 and the frame 14.
The door 12 is further connected to the frame 14 by door check means in the form of a stay 18. The stay is pivotally connected at a first end 20 to the frame by a bracket 21. A second end 22 of the stay is slidably connected to the door by a track 24. The track 24 is in the form of a generally L-shaped bracket. A generally vertical part 25 of the bracket is provided with a plurality of apertures through which is may be connected to the door by bolts 26. Any other suitable means of connection may be used. A generally horizontal part 27 of the track is provided with a slot 28 in which the second end 22 of the stay may slide.
In the illustrated embodiment a gas strut 42 is provided connected between the second end of the stay and the door. The gas strut comprises a cylinder 43 and a piston rod 46. A first end 44 of the gas strut is secured to the door 12. The piston rod 46 extends from the cylinder 43 and is connected at its free end 48 to the second end 22 to the stay 18 to move with the second end of the stay. As the door is opened, for example by a person located within the passenger cell, the length of the gas strut will increase to a maximum length corresponding to the door hinge A seiisor is provided to detect the presence of obstructions that would act to prevent the door opening freely. The sensor may be mounted in the door frame 14. Alternatively, the sensor may be mounted in the door assembly, for example, in a door handle assembly 50, a wing mirror assembly 52, a window frame 53 (Figure 2) or a rubbing strip.
Upon detecting an obstruction in the path of the door as it is being opened, a first signal is sent to the gas strut 42 to prevent further lengthening of the gas strut. This in turn will prevent further opening of the door by the person opening the vehicle door. Once the obstruction has been removed, or has been moved, the sensor will fail to detect the obstruction. The sensor then sends a second signal to the gas strut to allow the gas strut to be lengthened and hence for the door to be opened by the person to a desired extent.
It will be understood that the present invention can also be adapted to detect the presence of obstructions, such as fingers or coat tails, in the path of the door as it is closed, by the suitable location of a sensor, to prevent such obstructions becoming trapped between the door and the vehicle body.
In a preferred embodiment, the gas strut is fitted with a selectable valve (not shown). In the event of an obstruction being detected on opening of the door the valve can be selected such that it will prevent lengthening of the strut, but allow shortening of the strut so that the door may be closed. Similarly, in the event of an obstruction being detected on closing of the door the valve can be selected such that it will prevent shortening of the strut, but allow lengthening of the strut so that the door may be opened further to allow removal of the obstruction.
In an alternative form of the embodiment (not shown) an electromechanical device such as a clamp may be provided to act on the second end 22 of the stay 18 and for the frame 14 to prevent movement of the second end of the stay upon detection of an obstruction in the path of the door. Such a clamp may be used in addition to or instead of the gas strut 42.
It will be understood that the gas strut and/or the electromechanical clamp will be enclosed between the door 12 and the inner trim attached to the door, but omitted from Figure 1. Such a location provides protection for the gas strut and/or the clamp.
In an alternative construction, the stop means takes the form of a selectable clutch mechanism to control the movement of the stay 22 and thus the movement of the door. Under normal operation, the clutch will allow the door to be both opened and closed. On detecting the presence of an obstruction in the path of the door as it is opened, the clutch will be selected to prevent further opening of the door. On detecting the presence of an obstruction in the path of the door as it is closed, the clutch may be selected to prevent further closing of the door.
