Abstract
An airline safety seat is provided having a lap bolster for use adjacent a minor, such as a child. A retractor system consisting of two tension straps are connected to a male buckle adapter so that they may be pulled at the same rate as they pass over the head of a user and then buckled between the legs of the user. The tension straps are designed so that they may be fully extended without tension pull to engage a snapping pull so that they may retract and encompass a user thereof. These tension straps are connected to inertial rollers or reels mounted inside the lap bolster. The rollers or reels are suitably mounted. A buckle system is retracted into the lap bolster by the two inertial rollers or wheels. A male adapter system is pulled over the user's head and down the back to be buckled between the legs of the user to meet a female attachment. The female attachment extends approximately one inch out of the lap bolster. The portion inside the lap bolster is provided with a metal weight rolled at the end and a metal plate with three bolts preceding it to hold the system to the hard front face plastic. The metal weight at the end ensures a firm hold of the system. A strap retainer is provided to hold the straps close together and in place at the upper back of a user. The retainer is adjustable on the straps as desired.

Statement of the Problem
Children travelling on airlines have difficulty remaining in their seats while the airplane is in flight. Quite often, a parent will place a child in a seat of the aircraft, only to find that child has slipped out of the seat and wandering around in the aircraft.
Also, the aircraft quite often, does not have proper seat accommodations for children of various sizes. The result of this is that often a child is hurt or injured while in flight on an aircraft.
Also, if there is an airplane accident or crash, children including handicapped children or individuals may be harmed or injured.
Summary of the Invention
An airline safety seat is provided to protect small children and or handicapped individuals from harm in the event of an airline accident. The safety seat is compact so that all airlines may store the safety seats without any great loss of space. The safety seat is designed with safety in mind without being overly restricting to the individual.
A lap bolster is provided that is a self contained safety device which may be used in airliners for both infants and handicapped individuals. The safety seat provides a cushion as well as a restraint system to the passenger. The safety seat may be used as it is drawn to buckle between the legs or turned over to the reverse and buckle in front at the chest of an individual.
A plastic strap retainer is provided to hold the straps close and in place at the upper back of an individual. The retainer can be adjusted and moved about the strap system with some work when no tension is present. It is to be 4 by 2 inches and have four slit apertures so that the straps may pass.
A retractor system is also provided. It consists of two tension straps connected at a male buckle adapter, so that they may be pulled at the same rate as they pass over the head to then buckle between the legs. The tension straps will also have a workable stop tension so that they may be fully extended without tension pull, to then engage with a snapping pull so that they may retract and encompass the individual. The tension straps are connected to inertial reels mounted inside a lap bolster. One strap is positioned to the right and the other strap is positioned to the left to provide the restrain system. The wheels spin off one central bar which is mounted with a bent "S" shaped metal bar, bolted to the front face hard plastic facing. The wheels are again mounted at the sides with yet another metal plate system.
A buckle system is retracted into the lap bolster by the two inertial wheels. The male adapter system is then pulled over the head of the individual and down the back thereof to be buckled between the individuals legs to meet the female attachment. Fabric is woven over the male system several times to ensure a sturdy hold. The female attachment extends approximately one inch out of the lap bolster. The portion inside of the lap bolster is provided with a metal weight rolled at the end and a metal plate with three bolts preceding it to hold the system to the hard front face plastic. A metal weight at the end ensures a firm hold of the system.

Description of the Preferred Embodiments
Referring now generally to FIGS. 1 to 8 of the drawings, and particularly to FIGS. 2 and 3, there is shown a main and conventional aircraft seat structure 40 having two legs 42 and 44, a seat 46, and two arms 48 and 50. The safety seat lap bolster 10 of the present invention is shown installed on a minor on the seat 46 and between the pivoted arms 48. A seat belt S and a carcass 14 of a lap bolster 10, together with a sponge bolster wrap 16 (shown in FIG. 9) are shown in FIGS. 2 and 3, the arm 50 has been removed for clarity.
Referring now to FIGS. 1, 4, 5, 6, 7 and 8, of the drawings, the lap bolster 10 for holding a minor, such as a child in a safety position, is shown in greater detail. The lap bolster 10 is provided with a strap system 12 having right and left shoulder straps 20 and 22. The lower ends of the right and left shoulder straps 20 and 22 are connected to a bottom strap 24 and post member 30 secured to the lap bolster 10, as best shown in FIG. 4. The opposite ends pass through spaced slots 39 in the structure and are attached to their respective rolls or reels 38. A roller holding strap 36 shown in FIGS. 8 and 9 holds the rollers 38 in operative position, when an S-shaped roller clamp 34, best shown in FIGS. 8 and 9, is properly positioned.
The tension straps 20 and 22 are provided with a workable shop tension so that they may be fully extended without tension pull to them being engaged with a snapping pull so that they may retract and encompass a user, such as a minor. The tension straps 20 and 22 are connected to the inertial rollers or reels 38 mounted inside the lap bolster 10 as shown in FIGS. 8 and 9. There is provided one roller or reel 38 on the right side and one roller or reel 38 on the left side to provide a restraining system. The wheels for the system spin off of one central bar which is mounted with a bent S-shaped metal bar 34, bolted to a front face hard plastic facing. The rollers or reels 38 are again mounted on the sides with a metal plate system.
The lap bolster 10 is provided with a plurality of spaced seat belt retainer clips 18 on the seat belt S together with a clip retainer 19 for each retainer clamp 18.
As shown in FIGS. 1, 4, and 6, a strap separator 26 is provided to position the shoulder straps 20 and 22 a fixed distance apart in the lap bolster 10. This separator 26 is preferably formed of plastic and it is to hold the shoulder straps 20 and 22 close and in place at the upper back of a minor. The retainer 26 is arranged to be adjusted and moved about the strap system 12 with some work when no tension is present. It is (2" by 4") and has four slit holes so that the straps 20 and 22 can pass therethrough.
A spong bolster wrap 16 for the lap bolster 10 is provided as best shown in FIGS. 1, 4, 5, 6, 7 and 8, for protection of the minor child when in an operative position in the lap bolster 10.
The ends of the seat belt S of the lap bolster 10 are suitably secured to the sides of the aircraft seat structure 40, either by coupling clamps or the like.
The buckle system for the lap bolster 10 is retracted into the lap bolster 10 by the two inertial wheels or reels 38, previously mentioned. The male adapter system is then pulled over the individuals head and down the back to be buckled between the individuals legs to meet the female attachment. Fabric is woven over the male system several times to ensure a sturdy hold. The female attachment extends approximately one inch out of the lap bolster 10. The portion inside of the lap bolster 10 is provided with a metal weight rolled at the end and a metal plate with three bolts preceding it to hold the system to the hard front face plastic. The metal weight at the end is to ensure a firm hold of the system.
Accordingly, modifications and variations to which the invention is susceptible may be practiced without departing from the scope and intent of the appended claims.
