Abstract
This study investigated the parameters and materials needed to produce the child head and neck support prototype for a 3 year old in the 50th percentile range called Baby Heads Up. Preliminary simulations in SolidWorks were performed and the anthropometry measurements of the head and neck of children 2 to 3.5 years of age were utilized as a basis for the shape of the prototype. It was determined the materials for the base of the prototype would be high density lightweight EVA foam, with memory foam covering the center, and a cotton pillowcase woven to the shape of the prototype with a kid friendly pattern. It was necessary to ensure the appropriate material was chosen for the safety of the children and to prevent future recalls due to hazardous materials. Four different Aut°CAD designs of the base prototype have been completed and the final design has been entered into SolidWorks. The model was optimized and the design was improved based off of these results. A physical testing plan was developed to establish the desired variables such as the vehicle, car restraint, the angle, and different speeds for Baby Heads Up.
1.Introduction
Recently, the National Highway Traffic Safety Administration (NHTSA) and the Federal Motor Vehicle Safety Standards (FMVSS) have been involved in research regarding the effects of side impact collisions on children who are in child car seats. One of the major concerns of both organizations is head and neck injuries including severe brain damage. As a result, there have been discussions and meetings about implementing more standards for child car seats to include better protection to pedestrians during these side impact collisions.
Although there have been major strides in side protection being implemented in child car seats these restraints are expensive and not easily accessible to the majority of the households in the country. These factors indicate the need for a product to produce similar protection at a lesser cost which allows every child to have the protection they deserve, but at a price families can afford. The product developed allows the family to use their current car seat and place an additional accessory inside which provides the head and neck support needed during a side impact incident. It also helps the child...
