Description

Child restraint system for an aircraft

FIELD OF THE INVENTION

This invention relates to a child restraint system for an aircraft.

BACKGROUND OF THE INVENTION

Aircraft seats are typically provided with a simple lap belt designed to restrain an adult sitting in the seat. However, most airlines do not provide adequate means for restraining a child or infant passenger. For very young children, for example below the age of two, it is known to provide a belt attachable to the lap belt of a parent to restrain a child sat on the parent’s lap. Various crash tests have demonstrated that this arrangement is not safe for children and may result in serious injuries to the child in the event of severe turbulence, an emergency landing or a crash. Furthermore, restraining a young child or infant on the parent’s lap facing the back of the seat in front of the child is neither a comfortable nor pleasant experience for the child, which can lead to behavioural problems during a flight.

Larger children are expected to sit in their own seat, typically using the provided lap belt designed for an adult, which may not be appropriate for the child’s size, weight and age.

Some airlines allow parent’s to bring and use their own child car seats onto the aircraft. While this may be safer than relying on the standard equipment lap belt of the aircraft seat, such car seats are not designed for use with aircraft seats and are typically heavy and bulky and therefore difficult to carry.

SUMMARY OF THE INVENTION

The panels and associated straps of the harness portion can be fastened around the child and the lap belt fastened normally such that the harness portion 4 is attached to the lap belt and both the harness portion 4 of the child restraint system and the lap belt retain the child in the seat. The bottom panel 36 and crotch strap 50 of the harness portion 4 prevent the child from sliding out from under the lap belt of the seat in the event of an emergency.

When not in use, the harness portion 4 of the child restraint system may be stored within the sleeve 10 of the mounting portion 2. Fastening means may be provided for closing the open side of the sleeve 10 to retain the harness portion 4 within the sleeve.

When secured to a seatback of an aircraft seat in its first mode of use, the restraint system supports the child independent of the adult (seated in the seat behind that to which the mounting portion is attached), with the child supported on the seatback via the mounting portion 2. This leaves the adult free to read, use any device, or take refreshment, while facilitating interaction between the child and the adult and allowing the child to make eye contact with the adult. Amusement of the child may be further enhanced by the embellishment of the pouch of the harness portion 4 with accessories of audio and/or tactile nature.

In a further embodiment, as illustrated in Figure 10, the mounting portion 102, comprising a fabric sleeve 110 adapted to fit over an upper portion of a seatback of an aircraft seat, may be permanently attached to or integrally formed with, a harness portion 104 adapted to hold and support a child. As with the previous embodiment, the harness portion 104 comprises a rear panel 130 shaped engage the child’s back, side panels 132,134 extending from respective sides of the rear panel 130 to wrap around the child’s torso and engage one another in front of the child, and a bottom panel 136 extending from a lower end of the rear panel 130, said bottom panel 136 being adapted to extend between the child’s legs to be coupled to the side panels 132,134 in front of the child. The side panels 132,134 of the pouch preferably include apertures 138 for insertion of the child’s arms therethrough.

Again, as with the first embodiment, a strap arrangement is incorporated into the harness portion 104 preferably defining between them a three or five point harness for securing a child within the pouch of the harness portion 104, the strap arrangement including shoulder straps 142,144, optional waist straps (not shown) (which may be defined, at least in part, by the side panels 132,134 of the pouch) and a crotch strap (hidden from view in Figure 10 by the bottom panel 136), the straps being linked together to retain the child in the harness portion by a releasable buckle 152. The shoulder straps 142,144 are adjustable in length to enable the harness portion 104 to fit children of different sizes.

In the embodiment shown in Figure 10, the mounting portion 102 may included a strap or belt 160 adapted to extend around the seatback of an aircraft seat to secure the mounting portion 102 to the seatback and to provide additional support to the harness portion 104 suspended therefrom. The strap or belt 160 may be adjustable in length and may include a fastener, such as a buckle, for securing the strap or belt 160 around the seatback. As shown in Figure 10, the shoulder straps 142,144 of the harness portion 104 may be attached to the strap or belt 160 of the mounting portion 102.
