Abstract

ABSTRACT The point of the invention is to improve the safety of seat belt systems. For children's car seats in particular the device related to this invention prevents tampering with the intended position and function of the shoulder belts. Most typical is an additional harness with two ends attached to the present shoulder belts and a middle section attached to the back support. Due to a substantial width of the harness the areas underneath the shoulder belt are closed partially leaving restricted through sufficient large areas for the arms to be placed through. Closing mentioned area obstructs the child from placing p.e. the back of its hand between the shoulder belts and upper body in order to push the belts aside creating an unsafe situation and keeping it in the restrained position as intended by the seat's manufacturer it also improves support of the upper body.

Description

Title: A seat belt security harness.

Field of the Invention: The present invention relates to vehicle seats with a safety belt system. The invention particularly relates to children car seats where securing the function of the shoulder belts is required as children tend to flee themselves fiom a proper restrained position as intended by the seat's manufacturer.

Background to vention: Children's car seats commonly have a five-point seat belt system with a lock mechanism that connects all belts in front of the child at the level of the waist. This and similar seat belt systems are designed and considered as an adequate means for securing the child's safety in the case of sudden and unexpected manoeuvres or collisions of the vehicle. Typically these systems feature two shoulder belts that easily can be pushed aside by the child by starting to manoeuvre its hands underneath the belt fiom behind and subsequently pushing the belts outwards with the back of its hand. This action allows the child to move its upper body forward and ends with the belts sliding towards the back of the child. This creates hazardous situations by bringing other vehicle controls within reach of the child and also results in inadequate protection in the case of a collision. Existing solutions to prevent this often involve an additional strap between the shoulder belts in front of the passenger. These systems interfere with the ease of use and there for with the convenience and passive safety of the system.

The device mentioned in this invention addresses this problem in a reliable and effective manner. After placing the child in the seat and before securing the belts, the child's arms will have to be directed through the area underneath the shoulder belt as usual. Typical for the device mentioned in this invention is an additional belt or harness that is attached to the shoulder belts and back support. Being of a substantial width the harness partially cioses mentioned area leaving a restricted though suificiently large gap for the arms to be placed through comfortably. With the child restraint and locked it will typically find that its hands cannot access the gap between upper body and shoulder belts with the intention to push the shoulder belts aside. More so the harness improves support of the body sideways and encourages a proper upright position without interfering with the ease-of-use of the seat belt system. The harness does not interact with the lock or other safety features of the seat and it can be applied to seats where only one shoulder belt for the belt system is provided. The harness is simple to manufacture. It is easy to retro-fit and to remove but can also be integrated in the seat's design.

Statement of Invention: This invention relates to a device that comprises a seat comprising a bottom seat portion and back support portion, headrest, side support portions and safety belt system comprising a lock and belts. The belt system provides various safety functions including the function of two shoulder belts each attached to the top of back support portion at one end and joined with the lock in front of the passenger at the other end. The device typically features » an additional belt or harness attached to each shoulder belt whereby basically a restricted area is created underneath said shoulder belts through which the arm has to protrude before said shoulder belts can be placed in position and subsequently the lock can be secured. Mentioned harness can be of substantial width, from arm-pit down to waist level, in order to prevent the passenger from moving the hands between shoulder belts and upper body. The function of mentioned harness is to improve the safety of a safety belt system by offering enhanced support and by obstructing the removal of the shoulder belts when the passenger is in a restraint and locked position. firief Description of the Drawings; Fig 1: Fig la: Fig lb: Fig 2: Fig 2a: Fig 3: Fig 4: This figure shows a 3-dimensional front view of vehicle seat with security harness in place. The harness is of a substantial width and is constructed as a retro fit product consisting of a rigid middle section and two flexible end sections with their attachments to the shoulder belt.

Detailed Description: The device comprises a seat (1) that can be integrated or retro fitted in any vehicle in which restraining a passenger (2) by means of a belt system is desired. The device contains a seat belt system comprising a lock mechanism (3), waist belts (4), shoulder belts (S) and possibly a lap belt (6).

An additional harness (7) is attached to each shoulder belt at one end and to the back support portion (9) at the other end in such a manner that it restricts the provided area for the arms. This harness can have both ends attached to same shoulder belt thus forming a loop or ring through which the passengers arm is directed. Mentioned looped harness may comprise an additional strap (8) linking it with the back support of the seat. The strap keeps the harnesses face aligned with the surface area underneath the shoulder belt by preventing the harness from swirling around shoulder belt and there for improves ease of use when placing the arm through the loop formed by the harness.

In the particular case of two shoulder belts mentioned harness can also have one end attached to each shoulder belt forming an elongated element. For ease of use the harness can be attached to the back support of the seat whereby it can be can be seen as divided into a middle section (721) with means for attachment to the back support portion and end—sections (7b) that link the middle section with the shoulder belts. The attachment of the middle section of the harness to the back support portion can be done directly by means of Velcro, push buttons or the like. Attaching the end-sections to the shoulder belts can also be done by means of Velcro, push buttons or the like whereby the attachment also can be done in such a manner that an end section is allowed to move or slide along the shoulder belt. All mentioned means for attachment can be applied in a fixed or adjustable manner being part of the integrated design of the seat or as a retro fit-able product. The -rharness can be of a substantial width covering a large area underneath the shoulder belt fiom the waist up to the arm pit. The harness as mentioned above and all its sections can be made of rigid or flexible materials or a combination there of.
