7. The tripping element according to claim 5, wherein said actuation electronics system for generating the actuation signal evaluates a large number of sensor signals for monitoring vehicle states.
8. The tripping element according to claim 1, wherein said thermal circuit breaker trips in an event of a total current which flows across the current path which is greater than or equal to ten times a rated current over a tripping time of less than 20 ms.
9. The tripping element according to claim 1, wherein said thermal circuit breaker is configured as an opener without an automatic resetting means.
10. The tripping element according to claim 9, further comprising means for manually resetting a connected state with said thermal electrical circuit which is closed by means of the load.
11. The tripping element according to claim 1, wherein said thermal circuit breaker has a fusible predetermined breaking point for emergency, fail-safe isolation of the current path.
12. The tripping element according to claim 2, further comprising a limiting resistor for limiting a current and connected in series with said semiconductor switch.
13. The tripping element according to claim 1, wherein a status signal connection for checking a switching state of said thermal circuit breaker.
14. The tripping element according to claim 1, wherein said thermal circuit breaker trips in an event of a total current which flows across the current path which is greater than or equal to ten times a rated current over a tripping time of less than 5 ms.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A cushioning material that is arranged between a packed item and an outer box, the cushioning material comprising:
a base material that includes a main body portion which is brought into contact with a cushioned surface of the packed item and a bending part which is formed integrally with the main body portion so as to be able to be bent through a hinge line, the base material being arranged opposite the packed item; and
a plurality of columnar support portions that are arranged in a plurality of places on a surface on an opposite side to a surface of the base material in contact with the cushioned surface of the packed item,
wherein
the plurality of columnar support portions comprise
a first columnar support portion fixed to or formed integrally with the main body portion so as to protrude, in a thickness direction of the main body portion, from a face of the main body portion opposite from a face thereof in contact with the cushioned surface, and
a second columnar support portion fixed to or formed integrally with the bending part so as to protrude, in a thickness direction of the bending part, from a face of the bending part opposite from a face thereof in contact with the cushioned surface, with one end portion of the second columnar support portion protruding toward the main body portion beyond the hinge line, and
when the bending part is bent substantially perpendicularly with respect to the main body portion such that the bending part makes contact with another surface of the packed item adjacent to the cushioned surface, the first columnar support portion and the one end portion of the second columnar support portion both protrude from a surface of the main body portion toward a side surface of the outer box opposite the cushioned surface of the packed item by substantially the same amount of protrusion in a direction away from the packed item.
2. The cushioning material of claim 1,
wherein the first and second columnar support portions are arranged in a vicinity of at least three edges of the base material in three different directions.
3. The cushioning material of claim 1,
wherein the base material is formed with a corrugated cardboard sheet, and the first and second columnar support portions are each formed by stacking a plurality of corrugated cardboard sheet parts.
