Innovative Seat Belt with Integrated Booster Seat for Child Safety

This patent introduces a height-adjustable safety belt device designed specifically for dining chairs, combining protection with convenient storage and portability. The invention addresses the need for safer child dining experiences in restaurants, homes, and while traveling.

The Problem

Child safety during meals presents ongoing challenges for parents and caregivers. Traditional booster seats are often bulky, difficult to store, and cumbersome to transport between locations. Conventional dining chair safety belts may not accommodate children of varying heights, creating uncomfortable or ineffective restraint situations. The lack of integrated solutions forces families to choose between adequate child safety protection and practical convenience.

Current solutions fail to balance protection, comfort, and usability. Parents frequently struggle with adjusting existing safety devices to suit their child’s specific needs, leading to either loose or overly tight configurations. The absence of a compact, travel-friendly option means many families compromise on child safety when dining outside their home.

What This Invention Does

The patented seat belt with booster seat creates a unified safety system that addresses multiple pain points in child dining safety. The device provides height-adjustable functionality, allowing proper positioning for children across different age groups and sizes. By integrating the booster seat with the restraint system, the invention eliminates the need for multiple separate components.

The design prioritizes portability and storage efficiency through a compact configuration that allows the device to be easily folded or stored when not in use. This makes it ideal for families who dine out frequently or travel extensively. The height adjustment mechanism responds to each child’s specific needs, ensuring both comfort and proper safety positioning.

Key Features

Height Adjustability. The device includes an adjustable mechanism that accommodates varying child heights, ensuring proper positioning of the restraint system regardless of the child’s age or size within the target range.

Compact Design. The innovative structure allows for efficient storage and outdoor carrying, making the device suitable for families on the move without sacrificing protective functionality.

Integrated Booster Function. Rather than requiring separate components, the booster seat functionality is built into the belt system, reducing the total number of items parents must manage.

Secure Fastening. The safety belt incorporates reliable attachment points designed to work with standard dining chairs while maintaining consistent restraint during use.

User-Friendly Operation. The adjustment mechanisms are intuitive and require minimal effort to adapt for different children or positions.

Who Is Behind It?

Wonderland Switzerland AG is the applicant, with inventors YEH, I Ping, CHENG, Yu-Hsuan, and CHUNG, Chu-Hua contributing to the design. The patent is represented by Allens Patent & Trade Mark Attorneys in Melbourne, Australia. The application claims priority from two U.S. provisional patents filed in September and October 2024.

Why It Matters

Child safety products that successfully combine protection with practicality address a genuine market need. This invention recognizes that modern families require solutions that do not force compromises between safety standards and everyday convenience. The ability to adjust the device for multiple children within a household adds significant value for families with varying age gaps.

The portability aspect particularly benefits hospitality businesses seeking to provide child-safe dining options without requiring dedicated fixed installations. Hotels, restaurants, and travel providers can integrate this technology to enhance their child-friendly reputation while minimizing storage requirements. For parents, the investment in a single, adjustable device replacing multiple specialized safety products represents both economic and practical efficiency.

Related Concepts

Booster seats raise a child to the correct height for a standard seat belt or restraint system and are a key element of child passenger safety. Extending this concept to dining environments addresses a gap left by bulky traditional high chairs, giving families and hospitality venues a portable, height-adjustable alternative that does not compromise on restraint integrity.
