Vibrator/bouncer attachment for infant seats

摘要

An infant seat assembly is made up of a resilient frame with a leg rest portion designed to support a displacement mechanism which will either impart a shaking or bouncing motion to the frame; and, when a baby is placed in the seat assembly, the frequency of vibration imparted to the frame can be selectively tuned to be in harmony with the natural frequency of vibration of the frame when an infant is placed in the seat assembly.
