Method for detecting seatbelt positioning in a vehicle having a seatbelt assembly and the image sensor and vehicle having the same. The seatbelt assembly includes belt webbing with a predefined webbing pattern. An image sensor is configured to take an image of at least a portion of the belt webbing. A controller is operatively connected to the image sensor and has a processor and tangible, non-transitory memory on which is recorded instructions for executing a method for detecting positioning of the belt webbing. The controller is configured to determine a latch status of the seatbelt assembly as being latched or unlatched. If the latch status is latched, the controller is configured to take an image of at least a portion of the belt webbing with the image sensor. The method includes determining if the belt webbing is in a preferred position based at least partially on said image.

Detection of seatbelt position in a vehicle

A seat assembly for a vehicle includes a lower seat portion and a seatback portion. The seatback portion is selectively movable to vary the reclination angle of the seatback portion. The seat assembly is configured so that a first part of the lower seat portion rises relative to a second part of the lower seat portion so that the lower seat portion acts as an occupant restraint when a predetermined condition exists. Exemplary predetermined conditions include the reclination angle changing, the reclination angle exceeding a predetermined amount, and conditions indicative of an elevated risk of vehicle impact.

Vehicle seat assembly

A dual stage air bag suppression system based upon seat position. A deceleration sensor senses the deceleration of the vehicle during a crash/collision. If the deceleration exceeds a first threshold value, and the seat is rearward of a predetermined value, then the SIR Controller initiates a first/low stage inflation. If the deceleration exceeds a second higher threshold value, and the seat is rearward of a predetermined value, then the SIR Controller initiates both first/low and second/high stages of inflation. If the seat is positioned at a point forward of a predetermined position, then the SIR Controller initiates the first/low stage inflation only when the deceleration exceeds the first/lower or second/higher threshold value and suppresses deployment of the second stage. Thus the SIR Controller initiates the inflation stages not only based on the severity of the collision or deceleration, but also based on the position of the vehicle seat.
