Abstract

An extruded impact blocker and a substrate in the form of a door panel is disclosed. The impact blocker and substrate are coupled together by a snap-type locking engagement. The snap engagement is provided by a projection extending from the substrate engaging an aperture or recess in the impact blocker.

EXTRUDED SNAP ON DOOR IMPACT BLOCKER Abstract

         An extruded impact blocker and a substrate in the form of a door panel is disclosed. The impact blocker and substrate are coupled together by a snap-type locking engagement. The snap engagement is provided by a projection extending from the substrate engaging an aperture or recess in the impact blocker.

Description

         A door impact blocker is intended to provide additional impact resistance to a door. Current door impact blocker materials are typically various foams such as expanded polypropylene and polyurethane, or are constructed of molded polymers. Attachment of the current foam blockers to the door substrate includes applying (e.g., laying down) hot melt glue on the back of the door substrate and positioning or placing (e.g., laying) the foam piece onto the glue. A plurality of posts integrally molded into the door substrate extends through holes in the foam to initially locate the foam to the door. The door substrate is then placed into a fixture and the posts are heat staked, permanently attaching the foam to the door.

         Unlike conventional impact blockers made of foam and glued onto the back of a door substrate and then heat staked in place, the impact blocker shown in the Figures is an extruded polymeric article that snaps directly to the rear of a panel (e.g., a door panel in a vehicle).

         Referring to the Figures, an impact blocker and a substrate are shown. The substrate includes a raised portion (e.g., a rib, projection, extension, etc.). At least a portion of the projection includes a snap fastener or interface (e.g., a ramp and hook) for engagement with the impact blocker. The snap interface includes a member or finger that extends generally from th...
