Abstract

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.

Claims

1. A seat buffering device disposed on a base of a vehicle safety seat, the seat buffering device comprising:

a reinforcing component disposed inside the base, the reinforcing component having a plurality of lateral surfaces; and

at least one concave structure formed on one of the plurality of lateral surfaces, the 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.

2. The seat buffering device of claim 1, wherein the seat buffering device further comprises a plurality of reinforcing components and a bridging component, two ends of the bridging component are respectively connected to the plurality of reinforcing components.

3. The seat buffering device of claim 1, wherein the concave structure comprises a first contacting surface and a second contacting surface, the first contacting surface is adapted to contact against the second contacting surface when the reinforcing component is bent, so as to constrain bending deformation of the reinforcing component.

4. The seat buffering device of claim 3, wherein the concave structure is a V-shaped slot.

5. The seat buffering device of claim 1, further comprising:

a plurality of concave structures respectively disposed on different positions on one of the plurality of lateral surfaces of the reinforcing component.

6. The seat buffering device of claim 1, wherein the seat buffering device further comprises another concave structure disposed on another lateral surface of the plurality of lateral surfaces of the reinforcing component.

7. The seat buffering device of claim 6, wherein a plurality of sections is distributed over the reinforcing component along a longitudinal direction of the reinforcing component, and the concave structures disposed on different lateral surfaces are respectively formed on different sections of the reinforcing component in an interlaced arrangement.

8. A vehicle safety seat comprising:

a seat body;

a base whereon the seat body is disposed; and

a seat buffering device, comprising;

a reinforcing component disposed inside the base, the reinforcing component having a plurality of lateral surfaces; and

at least one concave structure formed on one of the plurality of lateral surfaces, the 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.

9. The vehicle safety seat of claim 8, further comprising:

a supporting leg disposed on a bottom of the base to provide an upward supporting force to the vehicle safety seat.

10. The vehicle safety seat of claim 8, wherein the seat buffering device further comprises a plurality of reinforcing components and a bridging component, two ends of the bridging component are respectively connected to the plurality of reinforcing components.

11. The vehicle safety seat of claim 8, wherein the concave structure comprises a first contacting surface and a second contacting surface, the first contacting surface is adapted to contact against the second contacting surface when the reinforcing component is bent, so as to constrain bending deformation of the reinforcing component.

12. The vehicle safety seat of claim 11, wherein the concave structure is a V-shaped slot.

13. The vehicle safety seat of claim 8, wherein the seat buffering device further comprises a plurality of concave structures respectively disposed on different positions on one of the plurality of lateral surfaces of the reinforcing component.
