Claim:
A vehicle child seat alarm for alerting a driver when a child is left unattended in a vehicle child seat, said alarm comprising: a pressure-actuated sensor removably positional beneath a seat liner of a vehicle child seat; a speaker electrically coupled to said sensor and being removably attachable to an outer surface of the vehicle child seat; a push button switch electrically coupled to said sensor and said speaker, said push button switch being removably attachable to a vehicle door; and a power source electrically coupled to said speaker; wherein said sensor generates and transmits a control signal when a weight equal to at least a predetermined weight threshold level is detected and the vehicle door is ajar, said speaker receiving said control signal and emitting an audible signal responsive to said control signal, said speaker emitting said audible signal until at least one said sensor and said push bottom switch are reset; wherein said sensor comprises a cover formed from flexible and water-resistant material, said cover defining a cavity therein; a housing formed from non-conductive material and including top and bottom portions positioned within said cover, said top and bottom portions being selectively engageable between compressed and equilibrium positions; a contact switch having upper and lower plates electrically coupled to said speaker and said push button switch respectively, said contact switch being centrally positioned within said housing wherein said upper and lower plates are directly conjoined to inner surfaces of said top and bottom portions; and a deformably resilient spring member positioned about said contact switch, said spring member and said top and bottom portions being slidably engaged to the compressed position when an infant is seated on the vehicle child seat, said spring member being sandwiched within said housing; wherein said upper plate contacts said lower plate when said spring member and said top and bottom portions are at the compressed position, said spring member being compressible along a linear direction parallel to a vertical axis.
