Component for a motor vehicle lighting device, connection arrangement, and method for releasing a connection arrangement

1 . A component for a motor vehicle lighting device, comprising:

a joining portion with an adhesive channel for forming an adhesive connection with a joining crosspiece of a second component, wherein the joining portion has a solvent channel connected to the adhesive channel, wherein the solvent channel includes a width that is less than a width of the adhesive channel, and wherein the solvent channel extends in a downward direction from the adhesive channel, such that solvent channel is in fluid communication with a lowermost portion of the adhesive channel and is otherwise closed off from an exterior of the joining portion until an access port is formed through the joining portion for the delivery of a solvent therethrough.

2 . The component of claim 1 , wherein the solvent channel extends substantially along the entire length of the adhesive channel.

3 . The component of claim 1 , wherein the solvent channel is connected to the adhesive channel substantially along the entire length of the adhesive channel.

4 . The component of claim 1 , wherein the solvent channel width is sufficiently narrow such that the solvent channel cannot be penetrated by an adhesive in the adhesive channel.

5 . The component of claim 1 comprising a housing or a cover lens of a motor vehicle lighting device.

6 . A connection arrangement comprising:

the component of claim 1 , the component comprising a first component; and

a second component, wherein an adhesive connection is formed between the joining portion of the first component and a joining crosspiece of the second component, wherein the joining crosspiece of the second component projects into the adhesive channel filled with an adhesive, and wherein the solvent channel is free of an adhesive.

7 . The component of claim 1 , wherein the width of the solvent channel is 0.5 mm to 2 mm.

8 . The component of claim 1 , wherein the solvent channel defines a depth of 3 mm to 50 mm.

9 . A component for a motor vehicle lighting device, comprising:

a joining portion with an adhesive channel for forming an adhesive connection with a joining crosspiece of a second component, wherein the joining portion has a solvent channel connected to the adhesive channel, and wherein the joining portion has at least one access portion which is provided for opening an external access port to the solvent channel via a bore, wherein the access portion has a rib structure which locally stiffens the joining portion proximal to the solvent channel.

10 . A method for releasing a connection arrangement of claim 6 , the method comprising:

providing a first component, the first component including a joining portion with an adhesive channel for forming an adhesive connection with a joining crosspiece of a second component, wherein the joining portion has a solvent channel connected to the adhesive channel;

providing the second component, wherein an adhesive connection is formed between the joining portion of the first component and the joining crosspiece of the second component, wherein the joining crosspiece of the second component projects into the adhesive channel filled with an adhesive, and wherein the solvent channel is free of an adhesive;

opening an external access port to the solvent channel by drilling into the first component;

injecting a solvent into the solvent channel via the at least one external access port;

waiting for the adhesive to soften by reacting with the solvent; and

releasing the first component and the second component from one another.
