Abstract
A magnetic bumper apparatus for constraining a vehicle closure to a vehicle closure interface includes first and second magnetic members configured for attachment to the closure and closure interface, and a non-magnetic bumper element interposed therebetween. Each magnetic member defines a plurality of spatially modulated magnetic fields (SMMF) in corresponding patterns to provide a cumulative SMMF attractive force and a cumulative SMMF repulsive force between the magnetic members and define a separation reference and an alignment reference. The magnetic members in magnetic proximity to each other constrain the closure to the closure interface with respect to the alignment and separation references to prevent contact between a closure surface and a closure interface surface and to define at least one alignment parameter therebetween. Constraining the closure to the closure interface may include resisting a non-magnetic force inputted to the vehicle to prevent contact between the closure and closure interface surfaces.
