Seat buffering device and vehicle safety seat having the same

摘要

A seat buffering device and a vehicle safety seat including the seat buffering device are provided. The seat buffering device is disposed on a base of the vehicle safety seat. The seat buffering device includes a reinforcing component and at least one concave structure. The reinforcing component is disposed inside the base, and the reinforcing component has a plurality of lateral surfaces. The at least one concave structure is formed on one of the plurality of lateral surfaces. The reinforcing component is adapted to be bent via the at least one concave structure when the base is impacted, so as to reduce impact force applied to the base. Buffering efficiency of the reinforcing component corresponds to the amount, the arrangement, and the angle of the concave structure. The plurality of concave structures is disposed on the same or different lateral surfaces of the reinforcing component in the interlaced arrangement.

1. A vehicle safety seat comprising:
a base; and a seat buffering device disposed on the base, the seat buffering device comprising:
a plurality of reinforcing components disposed inside the base, each of the reinforcing components being disposed in parallel with each other and having a plurality of lateral surfaces;a bridging component, two ends of the bridging component being respectively connected in transverse relation to the plurality of reinforcing components;at least one concave structure formed on one of the plurality of lateral surfaces for each of the plurality of reinforcing components, each reinforcing component being adapted to be bent via the at least one concave structure when the base is impacted, so as to reduce impact force applied to the base; andwherein the concave structure comprises a first contacting surface and a second contacting surface, the first contacting surface contacting against the second contacting surface when the plurality of reinforcing components are bent, so as to constrain bending deformation of the plurality of reinforcing components.
