US3719248A — Door lock, especially for motor vehicles

Claim 1

Independent Claim 160 words

A door lock, especially for motor vehicles, with a pull handle means and with an installation acting by means of forces due to inertia on movable parts, significant from a point of view of the mass thereof, for preventing the movement of such parts which would otherwise be caused by inertia forces, characterized in that said pull handle means is pivotally supported at one end thereof at a relatively fixed part of the door and at the other end thereof includes a rod-like connecting means extending into the interior of the door through an opening in an outer body panel, an equalization mass means, and means for pivotally supporting said equalization mass means in the interior of the door in such a manner that in case of a sudden change of the movement of direction forcing the equalization mass means toward the outer body panel of the door, it prevents a pivoting of the handle means in the opening direction.

Claim 2

Dependent Claim 160 words

A door lock, especially for motor vehicles, with a pull handle means and with an installation acting by means of forces due to inertia on movable parts, significant from a point of view of the mass thereof, for preventing the movement of such parts which would otherwise be caused by inertia forces, characterized in that said pull handle means is pivotally supported at one end thereof at a relatively fixed part of the door and at the other end thereof includes a rod-like connecting means extending into the interior of the door through an opening in an outer body panel, an equalization mass means, and means for pivotally supporting said equalization mass means in the interior of the door in such a manner that in case of a sudden change of the movement of direction forcing the equalization mass means toward the outer body panel of the door, it prevents a pivoting of the handle means in the opening direction.

Claim 3

Dependent Claim 160 words

A door lock, especially for motor vehicles, with a pull handle means and with an installation acting by means of forces due to inertia on movable parts, significant from a point of view of the mass thereof, for preventing the movement of such parts which would otherwise be caused by inertia forces, characterized in that said pull handle means is pivotally supported at one end thereof at a relatively fixed part of the door and at the other end thereof includes a rod-like connecting means extending into the interior of the door through an opening in an outer body panel, an equalization mass means, and means for pivotally supporting said equalization mass means in the interior of the door in such a manner that in case of a sudden change of the movement of direction forcing the equalization mass means toward the outer body panel of the door, it prevents a pivoting of the handle means in the opening direction.

Claim 4

Dependent Claim 160 words

A door lock, especially for motor vehicles, with a pull handle means and with an installation acting by means of forces due to inertia on movable parts, significant from a point of view of the mass thereof, for preventing the movement of such parts which would otherwise be caused by inertia forces, characterized in that said pull handle means is pivotally supported at one end thereof at a relatively fixed part of the door and at the other end thereof includes a rod-like connecting means extending into the interior of the door through an opening in an outer body panel, an equalization mass means, and means for pivotally supporting said equalization mass means in the interior of the door in such a manner that in case of a sudden change of the movement of direction forcing the equalization mass means toward the outer body panel of the door, it prevents a pivoting of the handle means in the opening direction.

Claim 5

Dependent Claim 58 words

A door lock according to claim 1, characterized in that a support bracket means is provided in the interior of the door adjacent the opening for the rod-like connecting means, said support bracket means carrying a pivotal lever means having an arm portion engaging at the rod-like connecting means and another arm portion constructed as equalization mass means.

Claim 6

Dependent Claim 79 words

A door lock according to claim 2, characterized in that a spring engages at the lever means, which urges the lever means into a locking position in which a recess provided in one of the two parts consisting of lever means and rod-like connecting means surrounds a nose portion on the other of said two parts, the spring force of said spring being able to be overcome during the opening of the lock by pulling at the handle means.

Claim 7

Dependent Claim 72 words

A door lock according to claim 2, characterized in that a hook portion is provided at one lever arm of the lever means constructed as bell crank, and in that said hook portion engages into a recess provided at the rod-like connecting means when the forces due to inertia of the other lever arm become effective, said hook portion being normally kept out of engagement by the force of a spring means.

Claim 8

Dependent Claim 56 words

A door lock according to claim 1, characterized in that the handle means is itself constructed as two-armed lever whose one arm constitutes a pull handle and whose other arm carries a counter weight at an extension thereof, a spring engaging at said counter weight whose force retains the handle means in the usual closing position.
