Lock assembly for a vehicle hood
View Patent ↗A hood lock assembly affording effective support in the closing direction of a vehicle hood is provided with flexibility, such that under a predefined overload, the hood is capable of additional movement in the closing direction beyond the normal closed position.
1. A lock assembly for a vehicle hood having lock parts which provide effective support counter to a closing direction of the hood whenever the hood is in a normal closed position, said lock assembly comprising:
a retaining part configured to be fixedly mounted on the vehicle hood;
a first member which is one of a latch and a counter latch part that is displaceable supported on the retaining part and is configured to latchingly engage with a corresponding element situated on a body of said vehicle for retaining said hood in a closed position; and
a second member which is one of a preloaded spring and a deformable impact-absorbing pad, and which holds said first member in a normal support position relative to said retaining part when said vehicle hood is in said normal closed position; wherein,
support forces produced by said second member in the event of an impact acting on the closed hood in the closing direction are restricted to a predefined design limit;
in the event of a load which exceeds said support forces, the hood is moveable beyond said normal closed support position.
2. A latching arrangement for a vehicle hood, comprising:
a latch or counterlatch member for engaging with vehicle latching components to retain said hood in a normal closed position; and
a retaining assembly on which said latch or counterlatch member is displaceably supported, said retaining assembly being configured to be fixedly mounted on one of said vehicle hood and a body of said vehicle; wherein,
said retaining assembly comprises at least a deformable component which permits displacement of said latch or counterlatch member relative to said retaining assembly, out of said normal closed position of said hood, in said closing direction of said hood; and
said deformable component gives way in response to application of a load which exceeds a predetermined magnitude.
3. The latching arrangement according to claim 2 , wherein said deformable component comprises a spring.
4. The latching arrangement according to claim 2 , wherein said deformable member comprises an impact absorbing pad.
