Abstract: An active head restraint arrangement comprising a head restraint cushion, at least one head restraint post and head restraint post guide connecting said head restraint cushion to the interior of said passenger seats; and a flip-up assembly associated with said head restraint post beneath said head restraint cushion. Upon activation by rear impact, the flip-up assembly flips upward and forward to protect an occupant's head and neck from injury. Since this active head restraint arrangement utilizes a flip-up motion, the head restraint has a lower initial height that is dynamically increased upon activation. This feature allows the head restraint to be smaller allowing an occupant to have a better view around the head restraint.

Abstract: A torqued, error proofed for installation, chuck free helical head restraint guide that includes a head restraint guide assembly with at least two stems, a button sub assembly, and a bezel. The stems include a helix at one end of each stem and a multi-point socket head, an open wrench flat, and/or an internal torx head and crush ribs at the other end. The head restraint guide also includes a motor vehicle passenger seat that includes an upper cross member of a back frame with upper and lower openings. The head restraint guide further includes a head restraint assembly with head restraint posts and a head restraint pad.

Abstract: A test assembly for evaluating vehicle head restraints comprises a carriage adapted to be coupled to a drive member capable of moving the test assembly, a head restraint coupled to the carriage and a manikin assembly having a head portion and a neck portion with an upper and lower end. The head portion couples to the upper end of the neck portion and the manikin assembly couples to the carriage at the lower end of the neck assembly. The head restraint is positioned adjacent the manikin assembly so that movement of the drive member causes the head portion of the manikin assembly to contact the head restraint. The manikin assembly may further include a load cell and accelerometer for evaluating the effectiveness and performance of a particular head restraint design.

Abstract: The present invention relates to a head restraint assembly providing four-way adjustment and having dual positive stops as well as a single ergonomic control. The present invention includes a frame and a housing that engages a portion of the frame. The present invention further includes a cam assembly disposed within the housing to provide fore/aft adjustment of the housing relative to the frame. The cam assembly includes a camshaft and at least two drum assemblies supported by the camshaft. The cam assembly further includes a contact plate extending parallel to the camshaft to releasably engage the drum assemblies. The camshaft is connected to the contact plate to provide releasable engagement between the contact plate and the drum assemblies. The present invention further includes a control member to engage the cam assembly and provide for fore/aft and vertical adjustment in response to user input.

Abstract: A vehicle seat includes a head restraint which limits the magnitude of neck deflection of a vehicle occupant during a rear impact collision. The head restraint includes a support member attached to the top of a head restraint post. The support member includes a convex surface shaped to substantially conform to the profile of an occupant's head and neck. The support member is covered by a resilient material such as foam. The foam thickness is reduced due to the presence of the support member. Reduced foam thickness in addition to the shape of the support member provides for reduced occupant neck deflection during a rear impact collision.
