Abstract: A device for use in vehicles for infants called a Stay Secur Seat. This device is comprised of a seat; an essentially vertical belt system to augment the existing seat belt; a means to connect the vertical belt to the seat; a means to removably connect the vertical belt to the existing seat support bar; and a means to adjust the vertical belt's length and resultant tension. A person normally has to accept the rear mount seats based on warnings associated with front seat air bags. The new Stay Secur Seat device features very few parts and is self-attaching. In operation, the new Stay Secur Seat device is easily affixed to the vehicle seat without the need of any special tools or fasteners. The device eliminates the need for the driver to continually monitor the rear seat to see the child or infant in the seat restraint.
