ABSTRACT:
A vehicle steering wheel (12) has the temperature of its normally gripped regions (16, 18) modified from extremes to acceptable values by a heat pump (20) with heat transfer occurring along heat pipe sections (22, 24) between primary heat exchangers (26, 28) at the gripped regions (16,18) and a temperature modifiable surface (33). Circuit apparatus (67) automatically energizes the heat pump (20) to provide heating or cooling, as needed.
