Abstract
Abstract A child's safety seat for use in automobiles has a chair type safety seat body formed by a resin molding including a seat portion, a backrest portion and a pair of lateral wall portions rising upwardly and forwardly respectively from the seat and backrest portions. Each lateral wall portion has an edge which is turned back while forming a U-shaped cross section with a substantially uniform wall thickness. The turned-back edge has downwardly and rearwardly directed sections. Outer lateral wall attachments made by a resin molding separately from the safety seat body are secured to the safety seat body in such a manner that a continuous outer surface is obtained. These attachments connect to the free turned-back edges of the lateral wall portions and extend to the rear ends of the lateral wall portions.

Claim 1
Independent Claim
307 words
A child's safety seat for use in automobiles, comprising a chair type safety seat body made by a resin molding and having a seat portion, a backrest portion, and a pair of lateral wall portions rising upwardly and forwardly respectively from said seat portion and from said backrest portion, each of said lateral wall portions comprising an initially downwardly and rearwardly open channel forming an edge section of the respective lateral wall portion, said initially downwardly and rearwardly open channel having a contour with a U-shaped cross-section extending substantially continuously along said seat portion and along said backrest portion, said U-shaped cross-section having a first leg merging into the respective lateral wall portion and a second leg forming a downwardly and rearwardly directed free edge, initially separate outer lateral wall attachment panels made by a resin molding separately from said safety seat body, each of said initially separate attachment panels having an approximately forwardly facing rim contoured to match said contour of said initially open channel of the respective lateral wall portion, so that said second leg and said initially separate panels together form an outer chair surface extending substantially uninterrupted from said free edge to rear ends of said lateral wall portions, so that an outwardly facing surface of said second leg extends substantially in a same plane as an outwardly facing surface of the respective initially separate panel, and means for securing said initially separate outer lateral wall attachment panels to said safety seat body in such a position that said forwardly facing contoured rims of said initially separate attachment panels fit with the respective free edge of said second leg of said U-shaped cross-section of the respective lateral wall portion in said seat body to provide a substantially uninterrupted outer chair surface which substantially completely closes said initially open channel of said U-shaped cross-section.
