Definitions
- This invention relates to the latching of the door of a vehicle, and in particular to the provision of a latching arrangement employing a safety cable that is designed to prevent the door opening upon impact such as in an accident.
- a vehicle door is provided with a latch for engagement with a keeper mounted on a door post of the frame of the vehicle, and with an internal and external handle for operating the latch.
- the internal door handle is located about 600 mm away from the latch. this distance being related to the length of the vehicle door. It is known to use a rod to interconnect the handle with the latch to open the door.
- the door may buckle in such a way and to such an extent so as to operate the latch and thus open the door.
- the present invention is based on the provision of an arrangement whereby an external handle of a vehicle door is connected to a latch thereof by a cable that has a certain amount of "slack" in its length. Since the cable is not taut, it does not extend in the most direct path, for example in a straight line, between the handle and latch mechanisms.
- an arrangement in which an external handle of a door of a vehicle is connected to a latch of the door for releasing the latch from a keeper thereby to allow the door to open, the handle and the latch being separated by a direct distance d.
- a cable is connected at one of its ends to the handle and at its other end to the latch to effect said releasing, wherein the cable follows a path of length D that is curved and extends between the handle and the latch, and wherein the ratio D/d > 1.1.
- a path is understood to be “curved” when, at least over part of its length and usually along the whole of its length, the path is other than a straight line.
- a curved path may be of regular or irregular shape, and may form a loop, so as to cross back on itself. The curved path may lie on. inside, outside or cross over an imaginary semi-circle extending between the relevant two locations.
- the cable may be a co-axial cable, and is preferably a Bowden cable, wherein an inner wire thereof is fixed at respective ends to an operating mechanism of the handle and of the latch, and an outer, protective sheath thereof is fixed at each of its ends to the door of the vehicle.
- the vehicle may sustain an impact that will deflect the cable to an extent that is insufficient for the cable to be made taut enough so as to operate the latch and thus to cause the door to become open.
- Figure 1 is a schematic side view of an arrangement:
- points Al and Bl of this embodiment correspond, respectively, to the points A and B associated with the handle mechanism 2 and latch mechanism 6 of Figure 1.
- a wire 40 for example an inner wire of a Bowden cable, is shown extending between the points Al and Bl over a curved path that is substantially bell-shaped and has two substantially-linear portions.
- the path of the wire 40 is appreciably longer than the (imaginary) straight line path 42 between the points Al and Bl.
- the inner wire of the co-axial cable may follow a different path, forming part of a circle shown in broken outline 44 that extends through the points Al and Bl .
- an inner wire 50 of a co-axial cable extends between points A2 and B2. corresponding to the points A and B associated with the handle and latch mechanisms 2 and 6 respectively of Figure 1.
- the wire 50 extends between the points A2 and B2 in a path that is curved to form a loop, the total length of the path followed by the wire 50 being appreciably greater than the direct, linear (imaginary) path 52 between the points A2 and B2.
- the cable of the arrangement of the invention may lie along a differently-shaped curved path between the handle and latch of the arrangement whilst maintaining the relationship D/d > 1.1 , as set out above.
