Abstract

A handle 16 for exterior use in a vehicle to authorize a mechanism (18) to unlatch an access door has a structural part (34); a cover (36); and a pair of sensors or switches (28, 29) between the structural part (34) and the cover (36). A first sensor or switch (28) to interact with one or more fingers of a user'"'"'s (26) hand (2) and a second sensor or switch (29) spaced from said first sensor (28) to be activated by a user'"'"'s (26) different finger or the user'"'"'s (26) thumb. The combination of the two switches or sensors (28, 29) signal the mechanism (18) to unlatch the access door and wherein the activation of only the second sensor or switch (29) in the absence of touching the first sensor or switch (28) authorizes a mechanism (18) to lock the access door. Preferably, the first and second sensors or switches (28, 29) are electrically coupled such that activation of both authorizes an unlatching of the access door while the activation of only the second sensor or switch (29) authorizes a lock only feature. Accordingly, the second sensor or switch (29) changes authorization from unlatch to lock dependent on the use or non-use of the first sensor or switch (28).

Claims

1. A handle for use in a vehicle to authorize a mechanism to unlatch an access door comprising:

a structural part;

a cover; and

a pair of sensors or switches between said structural part and said cover, a first sensor or switch to interact with one or more digits of a user'"'"'s hand and a second sensor or switch spaced from said first sensor to be activated by another digit including the user'"'"'s thumb, the combination of the two switches or sensors operatively signal the mechanism to unlatch the access door.

2. The handle of claim 1 wherein the activation of only the second sensor or switch in the absence of activating the first sensor or switch authorizes a mechanism to lock the access door.

3. The handle of claim 1 wherein the structural part is formed as a bump or depression in an exterior surface of the access door.

4. The handle of claim 1 wherein at least the structural part is rigid and non-moveable.

5. The handle of claim 4 wherein the handle is rigidly and non-moveably attached or otherwise secured to the access door.

6. The handle of claim 4 wherein the access door is one or more of a hinged door, a sliding door, a lift hatch, a tailgate, a trunk lid or a bonnet or hood of a vehicle.

7. The handle of claim 1 wherein either the handle or the access door on which the handle is formed or otherwise attached includes a key cylinder and mechanical opening latch to permit the access door to be opened overriding the sensors or switches in the event of a power failure.

8. The handle of claim 1 includes a housing portion and a pull bar portion, the first sensor positioned in said housing portion.

9. The handle of claim 1 wherein at least the first sensor or switch is an electro capacitive sensor.

10. The handle of claim 9 wherein the second sensor or switch is a push activated switch device.

11. The handle of claim 9 wherein the first and second sensors or switches are electrically coupled, the activation of both authorizes an unlatching, the activation of only the second sensor or switch authorizes a lock only feature, the second sensor or switch changes authorization from unlatch to lock dependent on the use or non-use of the first sensor or switch.
