Abstract
The present invention provides a system and method for tethering that may be used to keep a cushion properly positioned for side impact protection, particularly in vehicles with limited space rearward of the cushion. A tethering assembly provides tension to keep the cushion in place. The tethering assembly may include a tether with first and second ends attached together such that the tether forms a loop. The first and/or second ends may also be attached to a lower portion of the cushion. Upper and lower anchors may be attached to a vehicle surface near the cushion to slidably retain the tether. When the cushion inflates, the first and second ends move downward. The lower anchor may be a locking mechanism that restricts withdrawal of the first end. During deployment and impact of a vehicle occupant with the cushion, the tensioning assembly exerts tension to keep the cushion in place.
