Trunk lid lock with remote release

A deck lid lock with remote release adapted to be mounted to a motor vehicle structure and engageable with a lock bar comprising:

• a base plate;
• a solenoid pole piece affixed to said base plate;
• a solenoid winding surrounding said pole piece;
• an armature fixed for rotation with respect to said base plate about a first pivot, said armature having a first leg overlying said pole piece on one side of said first pivot, and a second leg positioned on the opposite side of said first pivot such that the center of gravity of said armature is located adjacent said first pivot whereby energization of said winding causes said armature first leg to be attracted to said pole piece causing said armature to rotate from a latched position to an unlatched position;
• first spring means acting on said armature second leg for urging said armature toward said latched position;
• a latch plate rotatable about a second pivot from a latched to an unlatched position, said latch plate having an arm engageable with said armature second leg when said armature is in said latched position, and free from engagement with said armature when said armature is in said unlatched position, said latch plate further forming a notch which captures and restrains the lock bar when said latch plate is in said latched position and releases the lock bar when said latch plate is in said unlatched position;
• a key cam rotatably carried by said base plate and having a projecting cam tab engageable with said armature to urge said armature second leg to said unlatched position;
• second spring means acting on said latch plate for biasing said latch plate towards said unlatched position whereby said armature may be moved to said unlatched position either by energization of said solenoid winding or by rotation of said key cam, thus enabling said latch plate to move to said unlatched position releasing said lock bar, and wherein when said deck lid is closed, said lock bar urges said latch plate to return to said locked position causing said latch plate arm to re-engage said armature second leg;
• and
• energy absorbing means acting on said latch plate for absorbing the kinetic energy of said latch plate as said latch plate rotates from said unlatched to said latched positions.

A deck lid lock with remote release adapted to be mounted to a motor vehicle structure and engageable with a lock bar comprising:

• a base plate;
• a solenoid pole piece fixed with respect to said base plate;
• a solenoid winding magnetically coupled to said pole piece;
• an armature fixed for rotation with respect to said base plate about a first pivot whereby energization of said winding causes said armature to be magnetically attracted to said pole piece to rotate from a latched position wherein said armature is free from connection with said solenoid pole piece and said solenoid winding to an unlatched position;
• first spring means acting on said armature for urging said armature toward said latched position;
• a latch plate rotatable about a second pivot from a latched to an unlatched position, said latch plate having an arm engageable by direct contact with said armature when said armature is in said latched position, and free from engagement with said armature when said armature is in said unlatched position, said latch plate further forming a notch which contacts and captures the lock bar when said latch plate is in said latched position, and releases the lock bar when said latch plate is in said unlatched position;
• a key cam rotatably carried by said base plate and having a projecting cam tab engageable with said armature to urge said armature to said unlatched position;
• and
• second spring means acting on said latch plate for biasing said latch plate toward said unlatched position whereby said armature may be moved to said unlatched position either by energization of said solenoid winding or by rotation of said key cam, thus enabling said latch plate to move to said unlatched position releasing the lock bar and wherein when said deck lid is closed, the lock bar urges said latch plate to return to said locked position causing said latch plate arm to re-engage said armature.

• a base plate;
• a solenoid pole piece affixed to said base plate and fixed with respect thereto;
• a solenoid winding surrounding said pole piece;

• and
• second spring means acting on said latch plate for biasing said latch plate towards said unlatched position whereby said armature may be moved to said unlatched position whereby either by energization of said solenoid winding or by rotation of said key cam, thus enabling said latch plate to move to said unlatched position releasing said lock bar, and wherein when said deck lid is closed, said lock bar urges said latch plate to return to said locked position causing said latch plate arm to re-engage said armature second leg.
