Problems solved by technology

Although the height of the outer head restraints is usually adjustable, the height of the rear center head restraints is usually not adjustable, which makes it possible for the rear center head restraints to be directly in the within sight of the driver of the vehicle
Rear seat head restraints are also often difficult to accommodate in vehicles with rear seat folds, as the head restraints may contact the front vehicle seats during this operation, interfering with the rear seat fold operation, affecting the final Folding angles, resulting in uneven surfaces after folding

Embodiment Construction

[0034] The following description is merely exemplary in nature and is not intended to limit the disclosure, application or uses.

[0035] refer to figure 1 , a rear center head restraint system 10 for a motor vehicle includes a head restraint assembly 12 shown in this figure in a non-deployed or stowed position. The head restraint assembly 12 includes a front head restraint portion 14 that is displaceable in an upward direction 16 and a forward direction 18 relative to a rear seat back 20, as referenced Figure 4 shown and described in more detail. The rear head restraint portion 22 of the head restraint assembly 12 is displaceable in an upward direction 16 relative to the rear seat back 20 thereby “concurrently” defining displacement of the front head restraint portion 14 away from the stowed position. In the initial stowed position shown, the downwardly facing lower surface 24 of the front head restraint portion 14 is in direct contact with the upwardly facing surface 26 o...

Abstract

A rear-center head restraint system for an automobile vehicle includes a rear seatback of an automobile vehicle. A head restraint assembly is mounted on the rear seatback and is moved between a stowed position and a deployed position. The head restraint assembly includes a forward head restraint portion displaced from the stowed position in an upward direction and in a forward direction with respect to the rear seatback. A rear head restraint portion is positioned rearward of the forward head restraint portion and is displaced in the upward direction as the forward head restraint portion displaces away from the stowed position. At least one headrest post is fixedly positioned within the rear seat back. A release mechanism connected to the at least one headrest post is operated to release the head restraint assembly from the stowed position.

Description

technical field [0001] The present disclosure relates to head restraints mounted on motor vehicle seats. Background technique [0002] Motor vehicles provide seat head restraints to reduce or mitigate cervical whiplash injuries in vehicle accidents. A motor vehicle may include a rear passenger seat for three passengers. Each rear passenger is equipped with a head restraint, which is supported on the seat back of each rear seat. Although the height of the outer head restraints is usually adjustable, the height of the rear center head restraints is usually not adjustable, which makes it possible for the rear center head restraints to be directly in the within the line of sight of the driver of the vehicle. Rear seat head restraints are also often difficult to accommodate in vehicles with rear seat folds, as the head restraints may contact the front vehicle seats during this operation, interfering with the rear seat fold operation, affecting the final Folding angles, result...
