Vehicle seat with features to enhance lap belt effectiveness

An assembly, comprising:

• a seat frame;
• a cross tube pivotably supported with respect to the seat frame;
• a flexible mat comprising a front edge and a rear edge, the front edge supported by the cross tube and the rear edge supported by the seat frame;
• and
• a trigger, the trigger in response to a forward force greater than a threshold exerted on a flexible mat deforms a bar extending across the seat frame raising the cross tube relative to the seat frame.

An assembly, comprising:

• a seat frame comprising two side plates connected by a front tube and a rear tube;
• two arms supported for rotation about the front tube, each arm comprising a cam lobe;
• a cross tube extending between the two arms forward and above the front tube;
• a bar extending across the seat frame and contacting each of the cam lobe, the bar is configured to prevent the rotation of the two arms;
• and
• a flexible mat comprising a front edge and a rear edge, the front edge supported by the cross tube and the rear edge supported by the rear tube,
• wherein a forward force greater than a threshold exerted on the flexible mat below the front tube deforms the bar away from the cam lobe allowing rotation of the two arms and pulls the cross tube upward and rearward.
