Abstract:
A door check apparatus for an automobile comprises a unitary check body containing a pair of compliant leaves and a guidance arrangement which is adapted to be rigidly mounted to a vehicle door. It also comprises a check arm containing cam surfaces and detent features which is pivotally connected to a vehicle body structure and is configured to slideably interface with the guidance arrangement of the unitary check body. The unitary check body is manufactured from a resilient material so that the compliant leaves are capable of storing and releasing energy in response to the movement of the cam surfaces and detent features of the check arm relative to the guidance arrangement. Rotary motion of the vehicle door relative to the vehicle body structure is checked with predetermined forces generated from the energy stored and released by the compliant leaves at positions determined by the relationship between the detent features of the check arm relative to the guidance arrangement of the unitary check body.
